MPI Tuner Anyone?
- Thread starter MPNick
- Start date
Thanks everyone for the advice!! I asked Nick to send me a map similar to what I need. So I will start there, and if I have to, download one that works better from the library. Then I will try to find someone with a dyno shop, and have them help if I am having problems getting the find tuning in there. Nick is being cool, also. He said to stay in contact and ask questions, so I can get it tuned properly. I am not exactly stock, and I do already have gauges. I took them out of my show car, so they have been there since I first brought my car home from the dlr. I do want to find an AEM UEGO wideband O2, however. I found a really cool one at one time, that is digital, and very accurate. I am going to look that one up, and use it if I can't find a programmable one like the AEM for a reasonable price. Do I need a programmable one, or can the MPI do all of this for me? I have a narrow band Autometer C2 series, along with a boost gauge, and soon I will have my Greddy Profec B Spec II to control boost and keep better track of it. I just have hard pipes, HKS SSQV, Injen/AEM hybrid CAI, and colder plugs. I am considering the plugs CorkSport sells, which are Platinum, but a step colder. I saw a post in here that the MPI does not like the NGK 7 or 11 copper plugs. I have those now, I will probably get rid of them. Other than that...the Greddy EVOII exhaust they used my car to prototype is due at the end of the month from Japan, and I will hopefully find some sort of downpipe/midpipe setup when I get that one, to free up airflow. So that is what I am going to need a map for, and what I am going to need to tune for. I am also going to need to factor in the dry, warm air around here, and the altitude and whatnot, correct? Again, thanks for all the hints. I may check out that soldering iron too, Linux...thanksLittle Beavis said:One person drive, one tune. . .that's the easy way to do it. . .maybe the "only" way!
If I had to tune and drive, I'd probably crash.
nictlg7, get a hold of someone's map with a similar setup and use that as a baseline. If you're basically stock, there won't be too many "changes" in the map and what changes there are will be small. You should see a lot of timing added or pulled or a lot of fuel added or pulled, so you might be "okay" until you can afford gauges to verify what you are doing.
As far as a shop tuning it, you are unlikely to find someone familiar with the software, so grab a friend and learn - you might as well become the local expert, it isn't too hard.
BTW, your car is pretty sweet 505. I had plans to do many of the same things you did, actually. I have to do a piece at a time though, because I am on a strict budget. Everything on my car now has been paid for by parts I sold off of my very expensive show car. I just sold that car to my exgf, so I have no more parts to sell. I was nice enough to give her everything that was on the car at the time, including my awesome stereo and suspension setups, which we were going to remove if we sold it to anyone else. It sucks that to be able to afford to mod these things properly, you almost have to do something illegal to pay for it. Haha...Late505zoom said:
.It seems to me the Nick is content on using the stock NB for tuning. It says in some of his other posts in this thread that the only WB he likes to use are the really expensive 8-wire ones on the dyno's. Also the fastest and Most Powerful MSP was tuned using just the stock NB.
Maybe that will save money, by not going with the WB for tuning at first. From Nick perspective it seems to work just fine and is safe for that matter
Getting a buddy to drive your car while you tune via the laptop, sounds promising also.
Just my 2 cents I got from reading up on some MPI info on the forums. But it still seems odd that everybody (I could be wrong) who has the MPI tuner is using some sort of WB gauge or NB gauge to aid with the tuning, even though Nick doesnt require it for tuning. Are we being a little Paranoidjust a thought

Has anyone ever seen these? I looked at them when I was tuning my old car. They would match my interior well, and they are "supposedly" wide band. I am trying to determine the best method for figuring out my a/f settings. I doubt my Autometer C2 is that accurate. It bounces around too much. Someone should sell me an AEM wideband O2 with the gauge/controller setup. Once their car is tuned in, do they really need it anymore? Just a thought....haha.

Most of us that have been boosting non-FI proteges for awhile are actually quite paranoid. Others have bit the dust for "little mistakes", so many of us are way overkill (me being one of them, I know that). Can't be too safe can you?Saban said:
I said before and I'll say again, if you aren't trying to extract every horsepower you can, you will be fine without all the fancy gauges, but they DO help.

It's frustrating for everyone who is just starting out tuning...I am lucky b/c i am very close to nicks shop...and can go down to have him help tune out my ride.igdrasil said:
Latley we have been testing some new things out..and everything looks very promising.
And for the Record. I am boosting at 10psi...My a/f with stock injectors is at 11.6-11.8. With no problems.

That is nice #'sacidbbg said:
The way it looks we may be able to run as much as 12psi on the stock injectors only. Charles and I have been working with his car with the stock injectors only. We have been testing what the open air filter and air temp sensor under the hood can do to the AFR. So far the changes we made have worked.LinuxRacr said:
The good thing being able to test Charles car is he does not care if he blows his engine or not, well that my take on it anyway. If things turn out as well as the tesing has gone most people will not have to run the extra injectors setup. Also no one would have to deal with the bigger injector bs and all of the problems that come with them.
Please let me know if anyone with the MPI Tuner needs any help at all.
Thanks again

Me of course...MPNick said:
This is my last chance to make the MPI run as it should be. I dont know about tunning stock injectors. Last time I tried....recording log files I remember running so lean that i heard some explosions and knock that may have contributed to the failure.
This engine im running has never been touched and Im very very very skeptical with this now.
I made the aditional injector setup, but they are close to the vics valves so...I dont know if the fuel is going to go down as they open or...continue thru the plenum.

What? (confused)MPNick said:
I care very much. I have seen people runninn 8psi with a t3 on stock injectors using a RRFPR!
So why is it hard to believe that the protege can handle a smaller turbo set at 10psi with stock injectors w/ proper tuning using the mpi tuner?
Chas(pissed)
The extra injectors are great for the big power. You do not need them for lower boost. No system can get you as much power from the stock injectors as ours and still have the car idle better then stock and no drive problems at all. You should be able to run alot of boost the stock injector only, plus you can fine tune the idle and part throttle.igdrasil said:
Get the MPI Tuner working right and you will see what other people are finding out. Do not make the short cut and only use it for extra injector and timing retard only. We have found that this way will never get you the best power. Yes you will need to tune a little more. It is not hard at all to do. I only know of one person who gave up on tuning it the right way and his car may never run 100% right.
You need to make sure you have things done right this time. Move the air temp sensor out of the engine bay. Make a box around the air filter. This will keep the heat out of it and the fan wash will not be a problem. This is no joke, it needs to be done. Do you have any air leaks?????? Don just say yes all is good and then have problems and wonder why. Take a whole day if you need to and get these things done. You are on your 3th engine now, I think Pat is in the lead with blown engines right now. Not sure if you want that crown[sorry Pat]. If you need help ask. You have alot of people on this forum with the MPI Tuner. It is better to make tons of post's with questions, then to post you lost another engine. For the love of God do not run high boost until you have your tuning dailed in. Running more boost to go fastest on a untuned car will only break it faster. Start with lower boost and work the fuel map. As you get the afrs dailed in you then raise the boost. Do not try to tune your fuel map up to a boost level. Raise your boost level to your fuel level. Good luck and ask for help.

I thought this was known from a long time ago.MPNick said:
What about venting the blow off valve to atmosphere? That falls under the same category.
