So I was talking to the guys at Carl’s Alignment shop the other day and was describing my never ending tuning woes when they advised me to either chip the GTX ECU that this BPT uses, or repurpose another ECU. According to these guys, an OEM computer module is more reliable and easier to use than other alternatives, not to mention cheaper. The cheaper part depends on if you are able to find someone skilled enough to do the work of fabricating one. Enter Carlos at BP Performance Specialty.
A few relevant specs about the car would go as follows,
1990 Mazda Protégé 4wd
JDM GTX engine and transmission swap
JDM ECU
460 RX7 injectors
Y code VAF
Vj20/Vf 8 hybrid turbo
I used the harness that came on the chassis, so I guess that would be a B8 harness modified by me for the 4 wire TPS sensor.
At the time of purchase, this Evo 8 upgrade cost me $695, not including the MAP sensor and adapter. (Ooo, MAP sensor) The links to those parts are as follows
At this point in the log you might get the impression that I go throwing money around like I have a lot of it. That is not the case. (lol) It wasn’t until one of our forum elders pointed at this that I decided to make jump. What sold me on this upgrade was the promise of a reliable, smooth running build. I really didn’t want to part out and sell so this is kind of the last chance for this car. If this new upgrade doesn’t satisfy me, I believe I can repurpose it to work with my other build. I asked Carlos about this and he was guarded with the information but made a vague offer of help. The fact that it was tuned for this car in the first place makes me think it can be done.
I don’t blame Carlos for being protective of this information because I’ve seen how ideas get consumed by the web. If you’ve never had a noob repeat your own ideas back to you, let me assure you it’s not a pleasant feeling. Respect the work, and respect the creator for investing his time and effort into the community. Props for a bad ass workaround to a vexing tuning issue. Thanks man.
There are some things I’m just not going to show. If you have questions about the making of the upgrade, I would direct you inquiries to the first link on the page.
I’m happy to have comments and questions but would ask that you ask yourself one question. That is, “am I adding value to this thread”? The way I see it, I’m helping a hacker help us. Your help is also appreciated. I benefit too because I'm no rocket scientist. Lucky for me I don't have to be.
