Hi there.
well... I've put a custom turbo setup in my LX. I'm running on the stock ECU for now. I've seen a pretty cheap msp ecu for sale here.
I was wondering if you guys think it'll help a lot the performance of the engine.
You know... Less lean probably with the msp ecu.
But, since there's probably more "options" on that ecu... Is there a possibility that my check engine lights up for stuff that my LX doesn't have?
Thanks

how are you doing your fuel now? i really hope you have something other than stock

lets put it this way: I'm surprised you're able to run the thing at all with the stock ECU. Get the MSP ECU. At any PSI you'll be running waay to lean with the stock ECU.

Ok, that's what I tought. It's been a month and a half that I run like that. As soon as I can hear the turbo spooling, my A/F gauge goes lean :o(
Nyways, I'll get that ecu and see what it does. I'll get a stand alone that this winter.

if i just cruise around, there's no problem. It's if, for exemple, I race a honda... lol probably that I do some damage.

Buy a MSP ecu
Now lets see pics of that setup you got

It's a basic setup with everything I need. I use smaller turbo than the one used in the msp. It comes from a mitsubishi eclipse or 3000gt / eagle talon. It has 18000k's.

if it's a smaller turbo it spools at lower RMPs, which is even more reason to get a MSP ECU asap.

My friend turboed his es protege. He is using a VW KO3 turbo and his setup is similar to the sts turbo setup. Exhaust mounted turbo. He is using the stock fuel system which is complete garbage even for a small turbo. Wwe're still working on how were going to do engine management. I would suggest doing internals on your mazda for the sake of saving your engine.

Wow is all I can really say. I haven't seen anyone run a stock fuel system on a turbo in a while. As cheap as an FMU is now I'm really surprized that you haven't at least done that. Get an MSP ecu, it's a lot better than what you are arunning now but if you could afford it go stand alone EMS.

The 2g ('95-'99) Eclipse/Talon also came with a Garret T25, just with a Mitsubishi flange and it is not ball bearing. Same potential though. All 1g ('90-'94) manual turbo DSM's (Eclipse/Talon/Laser) came with a Mitsu 14b turbo (step down from the 16g, like on the Evo's...) but is actually a BIG step UP from the t25. It can easliy make over 300 whp (even AWD). Great turbo though! Automatic 1g's came with a Mitsu 13b (or 13g, I can't remember). Again, another step down from the 13b (smaller housings and wheels). But still a good smaller turbo. The turbo 3000gt/Stealth came with two 9b's (in America, 13b's in Europe) which have the same housings as the 13b/g, but smaller wheels. Not a very capable turbo though. I'm guessing you either have a t-25 or a 14b.
Anyways, as long as he stays off boost, then he can keep his stock fuel as long as he wants...but then what would be the point? To properly do this, a bigger fuel pump is a must as well as a fuel pressure regulator (either rising rate (12:1 or whatever) or linear 1:1, depending on the setup). Bigger injectors might be in order as well, as would an AFC or some other way to 'control' the air/fuel ratio. A wideband should be a must, but most people go without due to cost. I think it is the most important tuning tool you can buy, even with the cost. New lines would be nice, maybe even fuel rail, but if you are only boosting a small amount (5-6psi or so), then you should be fine.
Bah, why does everyone think the MSP ecu is a viable form of engine management? It wasn't even that good on the MSP why would it work for a custom turbo kit? different turbo, therefore it flows different amounts of air per psi. Yes it is safer than just running your stock ecu, but why not at least get a FMU or RRFPR and O2 clamp to control fuel?

I guess because the ECU is just a swap in?
Its the simplest solution yes, but is it a good one? My tire has a hole in it, i'll just duct tape it...
