What EMS systems are there?

[505zoom]

We talked about the TM for more then a few times. I even offerd one to you at one point in time. It was about that time that you were planning on jumping to the darkside. I pulled back my offer after that.

Absolutely not. You sent linuxracr and I the same "revised" TM (we were the only 2 people who got that particular version). We both had the exact same issues with tuning the switch point. You sent him a new one, and at that time you told me that I would get one when linux confirmed that the new one was fixed... that was the last time I was ever told that I could get a replacement without buying it. What do you mean I went to the darkside so you pulled back your offer? What justification do you have for telling a customer (one that pretty much got MPI tuner sales off the ground for you in the msp market no-less) that they don't deserve a working product? What did I do to deserve no free replacement? I will even dig up my old PM's to you if you want to try and claim that you were offering a free replacement.

More driveable then the stock ECU using an FMU/clamp setup? If they are turbo, how were they getting fuel before? I agree 100% it should drive better with an EMS versus using the stock ECU and FMU. So just saying it drives better and gets better gas milage is pretty open.

I mean better than a bone stock P5 of better than a bone stock MSP. and better fuel mileage than those.

All piggy-back units are reliant on the exiting ECU to provide the fuel and ignition to the engine. For this reason they are bound by the limitations of the existing ECU. Fuel is typically modified by changing the load sensor or lambda sensor signal. Ignition is done by delaying or advancing the crank angle sensors signal. The piggy-back unit tricks the ECU into thinking that it is running under different conditions thereby allowing for a different output. The SMT is a VERY BASIC

Tim,

How driveable is a car that:
bucks when going into boost
drift's timing
throws CEL for going lean, to rich or misfire. MPI FOOLER claims EMISSIONS
Look what happens when a stock sensor goes bad. MPI FOOLER can't fool anymore then and BOOM

Sounds to me like someone needs to learn how to tune. I never once had a cel caused by the Mpi. Once you learn how to tune for the turbo module then you get no bucking either. Maybe someone just didn't give the unit a chance to work right?

And sense when is it New news that a piggyback "tricks" or modifies the signals to the pcm? All piggybacks do it, thats what they are designed for.
You guys make it sound like you are just learning this stuff.

Exactly.. Sense you are a Mazda tech tell us how many maps are stocked in the ECCV??
When the computer flips maps, timing, fuel,etc are changed..Guess what you have to do to your tune on a piggyback.

I don't think anybody short of the engineers that did the programming on it could tell you that.
I can tell you I spent several weeks datalogging and monitioring all the key sensors then making up resistors and boost pressure sensors to trick the pcm into doing things I wanted done. It worked great but couldn't compensate for itself. I then bought the Mpi. Which does the exact things I was trying to accomplish in a nice neat package. The Mpi does compensate for all types of situations using the stock pcm. Something a standalone only dreams about doing.

The Mpi changes signals before the pcm sees them. In that situation how would the pcm see some wacked out signal then alter the timing or fuel output to cause detrimental results? This is what you guys keep implying, isn't it? If this really were the case surely it would have happened by now, right? Everybody would have had a situation in which the pcm freaked out and their motors popped, correcy? If it were as unstable as you imply than surely you would have to re-tune every week?

No. It hasn't happened. People have gone many months without having to re-tune the unit. There is even one Brave Soul running 277whp on the stock rods with the Mpi tuning the timing. If that is on the ragged edge I do not know what is. Surely your doomsday theory of timing jumping to extremes would have happened by now if it were to happen?

Of the dozen or so I sold, EVERYONE got a check engine light.. I only installed and tuned 3-4 of them.. I can count on one hand the local guys to me with the MPI in and running that have CEL. You going to say the other 8-9 people fell to this as well? We also know you did some OTHER computer mods on your so talked STOCK setup. Do you not think the computer senses there is a problem when it's TPS voltage , coolant and O2 being clamped are out? The ECCV has a mean learning curve and it's known to figure out in time it's being fooled. The MPI you are looking for a 2.08 or so ANG voltage at idle and when you add or substract in that cell, the voltage might not change(or does and comes right back to 2.12 or whatever it is) so you RESET the computer. Since this has happened to myself and others, why is that? I thought it would make a change and not relearn. When there are 0 in the cel it's suppose to be running on the ECU's map.. Why doesn't it? The car will be lean or rich. The timing tables are out. I have sat there with a Snap On scanner and watched it.. You still think I don't understand it?
When I asked technical questions to Nick like," what the numbers represent" I get a BS answer of just add or subtract. I have always said the MPI is what it is. For the price it's not a bad unit. It's not a standalone and can not do what a standalone can do. Stop saying it's the best thing when infact it's limited by the stock ECU. I have kept my comments and feeling to myself about the MPI. I still feel it's a good unti for a low boost application. You might have to reset or retune, but for the price it's not bad. We are only here because Nick like's to take pop shots at other Vendors products with NO factual backing. Do you like it when I take pop shots at you? Of course not, you feel you need to come back as anyone does.

I never realized this was getting personal. Are you guys getting mad and clinching your fists while you read this stuff?
I have held my personal problems with people on this board, and will continue to do so. I suggest everyone does it. It makes us look more professional.

And for the record. I have installed 4 Mpi's and 1 Haltech. I am not an expert, and did most of the installs and tuning for free. I have never, ever, had a cel come on from the Mpi. I do get the occasional cel from the Haltech, but I have never tried tuning it(that will come this spring). If you are getting p0171, or a p0172, then maybe you are trying to make too drastic of changes at a time.

Of course, with the MPi you still can get cel's. How do you go about troubleshooting a standalone system when something goes wrong? Process of elimination?

Ive never got a cel no misfires, nothing I have had to lower my upper fuel limit to not hit the fuel cut ,big deal it works and works well. I have had no other issues . I bet if i got one of the standalones i would have way more issue with them then i ever would with the Mpi . No switch point issues for me . Goes straight into pulling .

Save target as for mov

Come on Beau, you know damn well the MPI can be tuned right! You've seen it run for months with no issues and you even admitted you were wrong about that. I understand your frustration and all, but You know I am going to defend the unit when someone makes BS claims like this. Show me the 2 local guys who have CEL's! I can only think of 1 that might have a CEL, and that can be taken care of easily. And yes, you do need the car working right in order to have the MPi work right. IMO, hiding a problem is not the way to go. If the car has a problem, it should be fixed, not hidden by and ECU reset

505--I have had every version of TM setup's in my car, even the one that allowed acidbbg to run 10psi on stock injectors. The switch can and was tuned out. The ONLY reason Nick ever came out with analog control was to try to please people that didn't want xtra injectors. From day one he was going to sell the MPI with them but people complained so he came up with the analog control. Had it not been for that, no one would have ever had problems with it.

 

[JBreed]

FYI... I own linux racers original TM. It has been on my car for about 6 months, and I have NO issues it at all with it. My car runs great with theMPI, and old TM.

Absolutely not. You sent linuxracr and I the same "revised" TM (we were the only 2 people who got that particular version). We both had the exact same issues with tuning the switch point. You sent him a new one, and at that time you told me that I would get one when linux confirmed that the new one was fixed... that was the last time I was ever told that I could get a replacement without buying it.

I don't know about the others, but the Microtech has it's own codes that tell you if a sensor reading is out of spec or if is detecting any other problem. It's not as sophisticated as OBDII obviously, but it's not "guesswork".

 

[BlkZoomZoom]

Thats pretty neat, does it have a light that comes on when it sees a problem?

 

[terbow]

I think u can have it trigger a light. On the aem u can turn the CEL light into a shift light so im sure its possible to trigger such an event. to what extent? i dunno.

Hey blk zoom zoom here the traction problems iam talking about . This is a mid 1st gear punch and spins all the way thru 2 and chirps third . (cheers) (hah) oh yea save target as its asmall one

 

[TurfBurn]

Yeah, it has a red warning light on the unit itself.. and it will turn lights on the dash display unit if you use one of those...

 

[BlkZoomZoom]

Thats pretty cool.

 

[daedalus]

Yeah, it has a red warning light on the unit itself.. and it will turn lights on the dash display unit if you use one of those...

Could i run this to my stock check engine light that i cut the wire to? (boom07) That would be pretty neat.
