In case you don't know there is an update for the MSP. Get rid of the jerking at low RPM's. FYI I had it done yesterday it runs much better.

 

That is true....I got the upgade with my 2003.5 MS2 and runs better

 

Any body know if there is an upgrade for the P5 ECU?

ZZOOOMM, I'll see next Sunday at Denny's in Prescott Valley.
There are 16 people signed up for the run so far.

 

would the ms2 ECU work in an ES and have any positive effects, and if so how much would it run?

 

to my understanding, it could be done fairly easily, however the cheapest I have found one new is about $750, and you will still hit the inherent limitations of a factory computer if you want to get serious about doing mods... Haltech makes a unit that works with our cars that is not a piggy back or anything, for about $1200(i think) but you'll have to learn a whole lot more about your car... hope this helps

 

by the way, the biggest positive effect with the mp3 'puter is about 10hp....

 

was that directed to my reply??? just wondering

 

Yes, but there is hardly any noticable difference. Take it into your dealership for the upgrade. It's called a PCM reprogramming.

 

yep- and for us its the mp3 ecu, not a msp protege, because the msp is turbo our car is not

 

thanks, just wondering
still trying to figure out the direction i wanna take my pro with the engine

 

yeah, i know the feeling- but i think i have finally decided to go all motor myself- seems like everyone is doing a turbo kit, and I want something different, especially since i am joining the scca to autocross my protege- wont do that as well with anything else

 

What else should I take to my dealer? Meaning any upgrades to chitty performance that they deem their fault.

 

If your rotors are rusting badly, they too can be replaced under warranty at the dealership. I took mine in for a oil change 2 weeks ago and they noted it and replaced them for me.

 

About how much do you think that would cost?

What all do they reprogram? What are the alleged benifits of having the PCM reprogrammed?

Thanks
Bill

 

It's under warranty. It will cost you nothing but the time it takes you to take it in.

The PCM reprogramming is for the variable valve timing. Apparenty this timing can be adjusted to reduce the "swirl" effect of the air/fuel coming into your engine and help to decrease the rattle at startups.

Honestly, I did not notice much of a difference but I would still take it in to get the latest programming.
