Is there a reason why nobody has tried using a non-turbo protege ECU+FPR/FMU?

[CustomMSP]

This just occured to me...why not? I mean it'll be like the guys who turboed their non turbo FS-DE. We wont be able to run the same amount of boost we can with the stock ECU, but still get close to the HP of what the MSP with more boost plus no hesitation and inconsistancy of the stock MSP ECU. I think everything else is the same on the P5 as it is on the MSP aside from the turbo? No extra sensors that I know of that will throw a CEL.

Lets talk about this.

I'm not sure how it is on the msp but the mp3 will throw a CEL with the p5 ecu

[CustomMSP]

Thats because the P5 ecu is looking for VTCS and the mp3 intake manifold doesnt have that...thats all. The MSP and the P5 engine configuration is Idential as far as I know aside from the turbo setup and injectors I think. Now that I think about it...if the injects are bigger as well, this could work out pretty good.

[Dexter]

its a thought. im sure someone wouldnt mind swapping ECUs.
i think StuttersC wanted an MSP ecu at one point... *shrugs*

[CustomMSP]

I'd love to try this, but I'm kinda low on cash and I'm on the road all the time for work... if anything brakes on me...My boost spikes to like 8psi stock, so I'd be in no position to really experiment safely. We'll see, maybe I can find a P5 ecu cheap. I don't think anybody could really use the MSP ECu other than another MSP. The fuel map is way to rich for stock P5/mp3 injectors i think.

[Dexter]

Stutters has a turbo kit on his MP3 IIRC

[CustomMSP]

We would need an ECU from a P5, because MP3 ECU doesn't have parameters set for the VTCS as it doesn't exist on the MP3 and it has advanced timing. Unless the person is willing to run with VTCS disabled. Might as well remove it at that point as it cause engine vibration/noise when the coolant temps are cold. One more plus is that our turbo is kinda small, so it should be fairly safe actually. Hmmm....

i think the injectors are idenical in all proteges. It sounds like it would work, but the fmu cant be used for higher boost. on your little t25 you might be able to get away with 8-10psi, but the protege FMU kits are all limited to 6-7 psi with stock fuel pump..

I think it would be a lost cause... the FMU isnt a good answer.. It worked great for me when i used it, but its not safe to fun high boost. Save up for the emanage or something else, that you can fine tune.
kinda funny... all us fmu protege are trying to get rid of our fmu's.

[Dexter]

yeah thats exactly what i was going to post about the FMU, but i figured with the T25 it wouldnt be that much of an issue as it i with the T3 setups

[CustomMSP]

Exactly! If the ecu swap plus the FMU is going ot get rid of the hesitation/surge/aggrivation/inconsistancy that is caused by the stock ecu...than that'll be perfect for me...Anyway, the fmu should be good for boost levels up to about 12 psi with the stock turbo, anything after that I'd run a stand along anyway. I say 12psi only because I just read on the forum by doing a search that the injectors are bigger on the MSP and the fuel pump is the same. Shit, i'll be more than happy with 9psi without all the problems I mentioned above.

[PaulMP3]

you might run into timing issue with the FMU and p5 ecu... and you will need and inline pump if you start boosting 12psi.. i dont know the cfm comparison to a t25 at 12psi to a t3.. Maybe i just can't picture how bad the hesitation is...

I remember a few knowledgable members say the injectors are the same... Ask turboge he would know.. he swapped his out.

You should just save up for some engine mgmt...

[low_psi]

yes, that's an idea, but a not very good one... sorry, fmu's are shitty fuel delivery units... its not worth the hassle of switching ecu's and adding a fmu just so you can run stock boost.

all 2.0L FS-DE's in the Proteges come with 280cc injectors.

[Speedy_Guy00]

hey dexter check you pm's

[CustomMSP]

Interesting...

[dominoy2k1]

hmm i need a new/used fmu as my fucking mf2 doesnt work anymore, anyone?
