Mazdaspeed Protege Ecu question
Does anybody have any information on the ecu coming out on the the new turbo Protege? Did they use a stock one or are the fuel and timing maps different from the ecu on the n/a 2.0?

Hmmm
Well I hope they do somthin to the ECU. Cause I don' think many people are going to be happy wit the stock boost setting. And if they don't get a A/F Meter they'll lean right into meltdown. Or hit the fuel cut and wonder "what wrong?" I could be wrong, but from my experiance first time turbo owners think "just turn up the boost to go faster" I am deffinately interested in upgrading my ECU but don't want to spend to much money.

Traveler has some excellent info on the stock ECU
Our engines run very rich A/F ratio at WOT. He says that this would be very good for a turbo setup to about 7-8psi. I know very little about turbo tweaking so you might want to send him a message

We'll probably learn a lot from what Mazda does with the Mazdaspeed 3. Seeing that the turbo will be a port installed option, I'm not sure if they could do anything with the ECU in advance. Although the LSD and larger axles would probably be installed on the assembly line in Japan. The ECU was slightly different on the MP3 also.

Yea I'm looking forward to see what happens. But I find it hard to believe that our stock ecu would give enofe fuel via the stock fuel system. I guess they could keep the stock ECU if they added a little more pressure. My old car was a AWD Talon TSi and I increased the the boost by 7psi over stock and was able to avoid boost cut by doing some minor tweekin. But then again that car came wit turbo. I dunno but I'll deffinately have my eye on the new turbo Pro.

They'll just reflash the ECU program with the new fuel curve needed for their turbo setup. Easy for them since they designed the ECU in the first place. Cost about $0 and will take them 5 minutes.

As long as the Callaway turbo system doesn't exceed the physical limitations of the stock fuel pump or fuel injectors, the stock ECU could be programmed to handle the system. The question is, can the stock fuel system handle the turbo, and what is going to be used to control it? We won't know until we get more information about the MazdaSpeed 3. It's another hurry up and wait deal.

From my experience my stock fuel system is more than enough for my 5 psi non-intercooled system. I run way rich all the time when in boost. I have run it up to 8 psi with no problems. SO yes the stock fuel system in the 3rd gens can handle it easy.

Hey Creig
How much did it cost for your turbo setup and how long have you had it? Thanks that makes me feel better about using NOS. But I'm not going with ZEX I will use Nos. Any advice about what Ignition i should use and should I retard the timeing?

I ran a 60 shot for a while on teh stock ignition and never had a problem. I've had the turbo on for about 2 months now with no problem. If you want to retard the ignition on the DIS system you need to get the MSD DIS-2 ignition unit just the retard box won't work on the new Proteges
