mpi tuner wiring help (N/A)

[rusty_mazda]

i need a better set of wiring instructions for the na tuner. i was having a shop install and dyno it, but they keep having problems. first they tried tuning through o2's and corrected the bottom end (i think), and then figured out they needed to be tuning through the maf. so they rewired it and now it's throwing a cel. somebody please help me, thanks

i have no idea where your from. but kooldino is the best. if you can, he's in jersey..might be worth your while to go there.have him tune it...there was a guy recently that came from canada to get his tuned through him...search kooldino..you'll see.

well, you won't run any codes, and will have a very stable vehicle with his tune. it's always a good idea. plus, you could meet some forum members.

If you have the NA module, then you cannot tune the MAF, only the O2. To tune the MAF you will need to get a different module from MPNick. You also have to remember that you cannot tune this car in closed loop, so no matter what you do with the MAF, if you ar ein closed loop, the car will adjust. There should be no reason why you can pull or add enough fuel via O2 tuning to get you where you want it.

When I tuned O2 with the Turbo setup, I was able to get a full point richer via O2 tuning, so you should be able to lean it out a full point as well. It can be done, they might be trying to "overtune" it. I can help with the wiring, but not via email, it is too frustrating. We can setup a time to get on the phone and talk it over if you want.

And Dana doesn't know as much about the MPI as he lets on, but he is pretty good with "his way".

well, i've driven his car, and met him in person. in reading all of his praises, i've never seen anyone say otherwise. i've heard many people talk bad about the original creator.. MPNick...soo.that should say something.

nick is who said i should be tuning via maf due to the upgrades i have, and who is Dana?

bigtim will hook u up he know's ton's about the mpi. he has help me when i had my turbo in my p5.

Whatever you say, cap'n. The proof is in the pudding:

Anyway, Rusty - what are your goals for your tune? Are you looking to advance timing and lean it out or what?

i don't know much about tuning, all i know is i want to most power out of the tune, through ignition, afr, cam gears, whatever, but i want it to be highly streetable. (daily driver) Looking for 140+hp. right now i'm at 133hp and 142pft, the tuner is hooked up (not sure if it's right), and i'm led to believe the lower rpm range has been tuned, "just having trouble getting control over upper rpms". was installed at a repitable dyno shop, and that's pretty much the low down

 

[xelderx]

Subscribing because I'm in the same boat. I just wasted $200 on dyno time and got zero tuning done on the MPI. If we can't get control over the closed loop function then the MPI is basically worthless on my N/A car. 99.99% of the time my foot will be on the floor. My car dips into the mid 11/1 range above 5,000rpm.

You cannot tune in closed loop period!! The only way around it is to kick it in open loop sooner so you can tune it. Like I said before, I will go over it on the phone, it's too hard to type the info out and get the point accross. If you have a different TM from Nick, then you can pretty much use the instructions in my sig to wire it up, you will just not have the purple or yellow wires. Have you tried them? I made then as I was installing an MPI, so they are accurate.

Dana--how about the guy with the forged motor that is gone because of fuel wash, with your tune??? Nobody ever wants to admit the bad things. IF your the man with the MPI, supposedly better then Nick, then why is it you can't understand the simple cirucit in the TM and you were trying to get me to tell you how it works? Trying to steal what Nick came up with huh? You were a better person before you started your little business and started to try to undercut everyone and steal other vendors products. Whatever you gotta do to make a buck right?

Oh yeah, if your way is so good, then why is it you only made 10 more hp then me with 3 more psi of boost? Don't gve me no crap about the MAF cut, because at 11psi on the dyno, you didn't have that problem, you got it when you went to 14psi. So from 8psi to 11psi you only gain 10whp??? Yeah, your way is MUCH better. Oh and I ran that same setup for 3+years with NO issues, how long did you run on the stock drivetrain??

"Dana--how about the guy with the forged motor that is gone because of fuel wash, with your tune???"

in danas defense, he never tuned his car, he never even touched it. all he did was plug off a vaccum leak, so make sure you have the right information before you go posting it on the forums.

BWAHAHAHA.

:bs:

You mean smo0f? First of all, not only did i not ever tune his car, which he'll tell you as well, but he didn't even have the MPI in his car. He blew it on a stock ECU. The only time I ever touched smo0f's car was when i plugged a leak in his intake manifold. Looks like your buddy MPNick is spreading some bs rumors around. Please edit your post and set the record straight.

IF your the man with the MPI, supposedly better then Nick, then why is it you can't understand the simple cirucit in the TM and you were trying to get me to tell you how it works? Trying to steal what Nick came up with huh?

Uh, last I checked, you were the one who was trying to tell me about the turbo module. I just asked you how the relays were switched.

You were a better person before you started your little business and started to try to undercut everyone and steal other vendors products.

Who am I undercutting, exactly? Nick? I don't sell the MPI Tuner, so it can't be him. And what products did I steal? None. So stop talking out of your ass. I have 3 TMs in my garage that people gave me, and if I was that interested in Nick's precious TM, I would have taken one apart and looked at it.

Oh yeah, if your way is so good, then why is it you only made 10 more hp then me with 3 more psi of boost? Don't gve me no crap about the MAF cut, because at 11psi on the dyno, you didn't have that problem, you got it when you went to 14psi. So from 8psi to 11psi you only gain 10whp??? Yeah, your way is MUCH better.

Oh, God. You love to bring this up every other week, don't you? First of all, that was 3 years ago. I've learned a thing or two since then. Second of all, that dyno was only a day or two after I got my motor together, so I didn't have all of my problems ironed out yet. On top of that, not only can you not directly compare our dynos due to the fact that we had completely different hardware (you had a bigger turbo, IC, etc), but I didn't waste much time tweaking my 11psi on the dyno fully knowing that I was going to 14psi anyway. On top of that, countless forum members have driven and/or driven in my car and have been very impressed with it. I ran a 13.3@108 last year, and I've done even more work to it since then. The car definitely has plenty of power, and the car alone is indisputable evidence of my abilities. What's your best 1/4 mile time? a 15.4?

Oh and I ran that same setup for 3+years with NO issues, how long did you run on the stock drivetrain??

I don't see WTF this has to do with anything at all, but I ran my car for over a year on my stock drivetrain with no issues. I then bought a motor to build up, and continued to drive my car with 8psi on the MPI. When the motor was finished, I swapped motors. Don't see where you're going with this.

You do realize that not only are you bashing an Authorized Vendor here, but you're spreading completely fabricated lies, right?

(ughdance)

 

[Bigg Tim]

Do I give a s*** you are a vendor......NO. In fact I think it's BS that you are a vendor and a mod, I think that's a confilct there, but whatever. The fact remains that you tune your way because you CAN'T tune the stock injectors. Maybe the MAP sensor method is easier to tune for you, but tuning the stock injectors WITH xtra injectors is the way to go. If tuning the stock injectors is not the way, then why put 4 xtra injectors in the mani?? Maybe to get the fuel delivered closer to the intake port then where the pre-TB injectors are? So you spent all that money to put them in the IM when you could have just had them pre TB and tuned the stock injectors. Remember dean?? 300+whp with stock tuned injectors + pre TB injectors? Sems like that is the way to go to me......and it's cheaper.

As for the TM, you did ask me how it works, specifically because you can't figure out how to keep the coils from frying. I heard that you buy a lot of coils, is that because you keep frying them or your people do? Asking me how that cirucit works so you can make one yourself is stealing someone's else product. Tell me that's not why you wanted to know.....you know it is. So since you know all about the MPI, get it to work RIGHT!!!!

Now back to the reason of the thread.........If you have the TM setup to tune the MAF and have the O2 clamp in as well, you will use the instructions in my sig, minus the purple and yellow wire steps. When you have it setup, you want to zero out the map and adjust the fuel calibration until you get 2-2.08v at idle on the analog output. Once you have this, the car is setup like stock and should drive like stock. Then you will have to adjust the switch point to kick the car into open loop when/where you need to tune. Once it's in open loop, you can adjust the fuel however you want because the ECU won't pull the fuel. No need to buy an O2 clamp or anything else, you have what you need.

If you don't have the TM setup to tune the MAF and the O2 clamp, Nick can set you up.

It's been over a year since I installed my MPI so I don't remember everything I did. I'm assuming the TM is the turbo module? My car is N/A so I'm not sure if any of this applies.

If you are indeed talking about me, I would LOVE to know your source. But for some reason I don't think i'll get an answer.

 

[Kooldino]

That's fine, but the forum rules protect against Vendor bashing, which is exactly what you're doing here.

The fact remains that you tune your way because you CAN'T tune the stock injectors.

No, I just think my way is better. If Nick could tune so well, then so many people wouldn't problems tuning his way. K.I.S.S.

If tuning the stock injectors is not the way, then why put 4 xtra injectors in the mani??

To ensure a more uniform distribution of fuel.

Remember dean?? 300+whp with stock tuned injectors + pre TB injectors? Sems like that is the way to go to me......and it's cheaper.

Sure, but it also took him race gas to get that power. He was putting down 270's with pump gas. On top of that, he had a lot of head work and such done as well. I never said you couldn't make big power with pre-tb injectors, it's just the way I prefer to do it at high boost levels for safety reasons. Focus does it too. I really don't see why you care so much about where my injectors are.

As for the TM, you did ask me how it works, specifically because you can't figure out how to keep the coils from frying.

Dude, I never even heard of the theory that the TM prevents the coils from frying until you brought it up to me. Sure, once you did, I asked you why, but it was never that big of a deal to me.

I heard that you buy a lot of coils, is that because you keep frying them or your people do?

Again, more BS that you're hearing. In the 3 years I've been running the SMT-6/MPI, I've only had to replace one set of coils. And the only reason that happened is because I took my car to a tint shop, and the guy left the key on (but the car off) the entire time he worked on it, which blew the coils after awhile.

Seems like you're on a mission to start some s***.

Asking me how that cirucit works so you can make one yourself is stealing someone's else product. Tell me that's not why you wanted to know.....you know it is.

Dude, if I wanted to know how that circuit worked, I would go down to my garage, unscrew the 4 screws, look at how the relays were wired, and be done with it. This would allow me to OMGCOPYTHESUPERCOMPLEXCIRCUIT if that was my goal here. So don't go spreading bs that I'm copying anyone's products when I've done no such thing. If I was "stealing someone's else product" as you so eloquently put it, then not only would I have played around with it, but I'd be selling said product.

So since you know all about the MPI, get it to work RIGHT!!!!

I do, and my customers are very happy with it. Many of them went to Nick before they went to me, the cars started acting up ON THEIR RIDES HOME, and they had nothing but headaches after Nick "tuned" their cars. I've seen his tune maps first hand. They're a total joke. The cars buck and surge, they cut power, CELs come on every 5 minutes, they drive poorly, etc. It's a nightmare.

The main difference between tuning Nick's way and my way, is that my way, the extra injectors inject a little more fuel than they do Nick's way. However, while Nick's way doesn't directly control the stock injectors, it often leads to tuning issues, where as my way doesn't interfere with them, and allows more straightfoward control of things. I don't think those differences warrant attacking me over. You can read everywhere (like in this thread) how people have problems with doing things Nick's way, and I've yet to see a thread of someone having a problem with tuning my way.

Anyway, thanks for apologizing for blaming me for blowing the engine of a guy's car that not only did I never tune, but who doesn't even have an EMS installed.

(poke)

My apologies to Rusty for the threadjack. I just had to defend myself here.

 

[BBSF2]

again, in danas defense, his tunning is very good and has kept me happy for almost a year. i boosted my car last january, and started running it at 7psi. dana tuned it for me, and i was loving it. went to the track, and ran a 14.8 at 97. i was happy, but dana wasnt. i went back to him 2 months later, retuned the car for 10 psi, and damn, this car was fast. after that, i was convinced that dana definetly knew how to tune, not because it was fast, but because my car has 100,000 miles on it, and it pulls stronger then ever, which means that his tune is not only good for good power, but its also good for a RELIABLE driver. if i had to deal with bucking, CEL's, and other problems, i would have proally sold the car due to the fact that i would not have been happy. im just posting this because ppl need to know what dana is all about. he tunes a little different then nick, ok, but really, if one works better than the other, just done differently, whats the big deal??

(poke) Tim are you F***in kidding me you have no idea how many people Nick Screwed of money including my self and I can probably name 5 more but I don't wont to get them involved. I paid Nick $800 and my car was running like s*** leaning out and bucking / CEL all the way home from Nicks shop . Dino would never let car leave his garage Half ass. So in my eyes Nick has NO clue what he is tunning. Tim stop talking BS about Speed Circuit, cause he puts 110% in anything he does. I dont think Dino's way of tunnig is so bad? @ 10PSI on GT28RS on stock motor I Ran 13.9 @ 1/4 mile (first)...
