MPI Tuner Anyone?
- Thread starter MPNick
- Start date
A little info to add to this.. im not getting involved but..
Wagner installed my mpi tuner, and did base tuning with it. I had issue with the stock computer pulling fuel, but it stop eventually. Others say they never had this problem. Even when the stock ECU pulled fuel, my AFR were always dead on because i added fuel, and tuned using my wideband. my AFR are exactly where i want them. And i tune the car myself, wagner doesnt tune it for me. My car is fast, and runs great, my only concerns are my timing maps, but MPnick offered to look over them for me. I am paranoid for the most part, i personally believe i am pulling to much timing, i have only witness detonation once, and it was b/c some bad gas while running 12psi on 94 octane around 6000 rpms. i tried to stay off boost throught that tank, and never heard anything again.

Also...When tuning using the laptop..how much are the readings off..as compared to the readings w/ your wide band? can you send me a datalog?paulmp3 said:My A/F is between 11:1-12:1 the whole time it drops down closer to 11:1 after 5000rpms. no hesitations at all. Its really fast
My egt readings are no higher then when i ran 5psi on the FMU.
Also you are using extra injectors..right? Any issues while driving in the city w/ out boost?
B/c i wanna understand how akilleis is stating that your unit isn't running very well!

Car runs 100% perfect off boost. usually stays in close loop while off boost and afr reads 14.7 majority of the time off boost. Yes im using extra injectors.
I got 24mpg all city driving, last fill at 12psi.
last trip i took i got 32 mpg on the highway, boosting occasionally. I contribute this to the WB, during long trips i try and keep the AFR steady at 14.7 to achieve maxium mpg, except when boosting or climbing hills.
I mentioned to akilleis about my problems i had with the ECU pulling fuel in the begining. I also mentioned to him "I personally" wouldnt run the unit without a wideband, b/c of the changes i had. No one else seem to have these issue, kooldino had some issue, but mine seemed to pull more fuel then his did.
The AF display bounces around so much with the tuner software, i dont look at it. I will check it out for differences and data log next time i tune. Maybe this weekend if it is nice out

Yeah this weekend is really supposed to suck..6inches they are calling for!paulmp3 said:Car runs 100% perfect off boost. usually stays in close loop while off boost and afr reads 14.7 majority of the time off boost. Yes im using extra injectors.

Thanks for keeping it real! I just think it's important to know..that this unit..indeed does work..as long as you properly tune it! I am planning to get dyno'd after i get the ic on..to get all a/F ratios to their respective numbers!

I am not trying to flame you but..with any piggy/stand alone..there will alwayz be tuning..it's been said many times "No 2 cars are tuned the same" Why b/c each protege has something different..from different size injectors, turbos, exhuasts, intake, intercoolers, manifolds, bov..etc. etc.akhilleus said:
And it's very simple to tune..i am a newbie when it comes to tune..but its point and click with nicks software!
Chas
You keep forgeting that you have to adapt your engine management to whatever car you are using. Once you get it running, you can add/release more compatible features to improve the product. Isn't this the same thing that Perf is supposed be doing with the AEM? Upgradability! And to answer your other question...Why didn't MPNick tune it for him? He can send them a base map, but it is hit and miss. Until he gets his hands on the car or datalog for tuning, he can't be exact to a specific car. The same goes for the AEM. Folks can claim they can pre-tune it for you, but every car is different! No two protege's are alike!akhilleus said:

I have had my mpi tuner in for a couple of months...nick initially tuned it..but i had some minor problems..which i needed to tune..first..had a problem w/ my primary o2 sensor (long story..but basically the way the wiring was installed caused it to burn wires..very messy)..which kept tripping cel...also problems with my maf being to close to the BOV!akhilleus said:
None of which had to do w/ mpi nicks tuning..rather another individual's install and design of my turbo kit!
Anaywayz..paul has had his unit about 2-3months before i did!
Chas
Yes but the base maps on the AEM can be much more precisely tuned. And the wiring is very clean. I know that the mpi tuner is fine for basic duties but the AEM is entirely more advanced. Enough.. Perf is about to demonstrate it soon.. I have seen it working ... u have not. then we will see.
DAMN, this thread got busy. How many more people do you need to see with the MPI working to prove that it works???? If you have never used it, then you can't say how it works, you are only basing your OPINION off of what someone else "thinks" he knows about it. I've had this in my car since August. The first 3 months don't count because your boy gave me bad info on it. So then I've had it in for about 5 months and it does EVERYTHING it's is supposed to do.
You CAN control the stock injectors, who cares how, all that matters is you can change how much fuel the stockers put in. You think the extra injectors don't work, but look in the new turbo mag, you'll see there that they work. How about that picture of the Viper with them???? Some people won't listen no matter what proof is given.
If Perf designed it or developed it, then how come he gave me bad info on how to get it working or tune it for 3 months??????? I just hope he learns enough about the AEM so when/If it's released, no one will have these issues. MPNick has been using these things for years and knows a great deal about them. I personally would rather go with years of experience, rather than months of book reading.
