MPI or something else??

[03.5MSP]

I know the MPi and its functions have been discussed before and i read most of the threads about the MPI.

I currently have aem cai, perrin fmic, apex 2.5 dp w/hf cat, greddy sp2 catback, and corksport s-pipe soon to come.

Any way my long term plans are to build a block and have about 300whp. But before I do that I know I cant reach my goals without an ems.

So would the MPI really be the way to go??, or should i consider something else. I dont have the money for an aem ems or haltech ex6 since both are above or around $1500.

I dont plan to tune it myself, but instead plan to get it dyno tuned at 10psi when I get my ebc. I know that most people runnin big HP are using the MPI and thats why I'm leaing twards it.

Your opinion are greatly welcomed.

MPI and a wideband. Tune it yourself. The worst that can happen is you blow the motor...

 

[apocman]

MPI all the way....

lol

Yea with the increased knowledge base for the MPI on Proteges, and the great help on this forum, I would get MPI all the way. But yes you will need a WB O2, everyone should have one. I should have one...

I guess the MPI will probably be my choice. How hard is it to install and does anyone have a howto yet??

 

[apocman]

we have a how-to, but are in the process of making new ones and you can pm us for our cell numbers to walk you through it as you do it.

^^^ awesome

Buy an EIC and J&S... samething.

 

[livelyjay]

Go with the Airflow Logistics AFC for now, then down the road when you get the block and such sell the AFC and then get the MPI. That's the path I am taking. You should also get a WBO2, because tuning without one is not smart, and having to go to the dyno to tune is a pain.

Please explain this statement, and is it much cheaper?

 

[BlkZoomZoom]

It's not the same thing by any means. Not even close.

MPI is Great for the money and has been proven to put down some serious numbers if tuned right. It will take some patients while tuning but the support an knowledge from other members is out there and that makes things alot easier. I will tell you this make sure you dont currently have any problems with your car because it will make things alot harder to tune the MPI and the MPI will make those current problems more pronounced and worse if not fixed. Be sure to pick up a wide band if you have the money it will also make your tuning alot smoother and easier speaking of which I need to get myself one. I would say pick up the MPI you will love it!!!

 

[apocman]

I say buy a MPI and J&S!!!! MPI for engine management and J&S for true knock defending... I think the J&S is a great addition whatever EMS route you go...

 

[Moeed]

Oh yea, you will need patience. tuning is not an instant process, and it takes a while and a good stretch of road to really fine tune a map. Good luck, I have some instructions that I reordered. I will add pics to them too. For me they flowed better than the ones that come on the cd.

 

[03.5MSP]

I think the MPI is really the way to go, and like you guys said alot of members on the forum have it and love it. I am hoping to get a wideband as well, but as far as the tuning I actually wanted to get it dyno tuned. But then again that will be more expensive.

MPI is a great system, but in my opinion the value just isnt there anymore. after you drop 660 bucks on the unit, and 320 bucks on the aux. injector support you will need to hit 300whp, you have spent 980.00 and are still using a piggyback and having to deal with the stock ecu which is a ******* ***** and a half.

Microtech standalone = 999.99 right now, and includes a MAP sensor. Do the math, spend 19 more dollars and dont ever have to worry about upgrading your EMS ever again. Also, with the microtech, if you ever wanted to part out your car and tune another vehicle, its a standalone so you can reuse it, the mpi wont just work with anything...

Just my thoughts. Both are great systems, i just feel that the MPI doesnt have the value it used to. Based off your goals, standalone would be best.

 

[Mr. Win]

Your right... im more with dadelus on this one, the value is just not there. MPI cant control bigger injectors, so you have to add a fuel rail or an AUX setup. The interface is odd, from what ive played with. In order to get it to work right you have to do some odd things with it.

Other options:
DSM AFC and J&S
EIC and J&S
or Megasquirt (never worked with it)

Most feel J&S is very good to have anyways.

Dont get me wrong its had sucess but for what most people want i think there are better ways about it and if you looking to run anything above 280ish standalone would be better.

It's not the same thing by any means. Not even close.

Very good point, I will have to consider the Microtech now. The only thing keeping me back from standalone is that they are a b**** to tune. Thats my guess maybe I'm wrong.
Also if I put 440 cc injectors the mpi wouldnt be able to control them??

 

[apocman]

I understand all EMS/Piggybacks have their drawbacks, but until one other EMS/Piggyback can show real-world dynos or qauter mile times that match beat or exceed the MPI, which as far as I know nobody has been able to do yet. Then the MPI is the WHP and QM Time king!!!

also you can get the MPI for $580 shipped and extra rail setup for $285 shipped, if you work with Nick

I think you'll be happy with any EMS/Piggyback system you choose, but MPI is fact proven king until others can beat it...

Disclaimer somebody may have, but I haven't seen it yet

 

[Mr. Win]

ummmm the microtech has to be one of the most user friendly ems to tune. You will be doing the samething with the MPI... its just not as pretty/easy.

I have not heard of anyone being able to use larger injectors without problems on the MPI.
