I have a 30-1710 AEM Plug and Play that I am installing in my boosted 90 Miata. I hope to accomplish two things with this thread:
- Get many questions answered.
- Create a thread that is useful for anyone else who attempts the same. It would be great if this could evolve into a build thread or perhaps an "AEM Standalone Install for Dummies" thread (only I'm currently the dummy).
In the interest of keeping everything organized, I plan to list (in the second post of this thread) all of my questions in an ordered list. Once a question is answered (or if I figure it out on my own), I'll strike it through and reference the post where the answer occurred. That way, anyone can land on the first page of this thread and see which problems have been addressed and which are outstanding. I figure that if I am going to beg for help, I should at least make it easy to navigate.
Here are the details about my car and the setup:
- 1990 Miata
- 1.6 liter with stock internals
- Flyin' Miata turbo kit with GT3071r turbo, intercooler, etc.
- 440cc injectors
- I will be running E85
- Coilpacks from a 1.8 (the previous owner did this and I don't entirely know why)
- AEM Plug and Play standalone 30-1710
- AEM jumper harness (the harness that simply extends the factory ECU wiring harness... I intend to use this for all wiring changes rather than hack up the stock harness)
- NGK Powerdex wideband O2 sensor and "brainbox"
- Motec 3 bar map sensor
- Boost solenoid
- Intake air temperature sensor
- A rather questionable aftermarket fuel pressure regulator
- Various supporting mods (clutch, torsen diff, big radiator, etc.)
I would like to make at least 220 whp but obviously I'd prefer more. I will have the car tuned by Tony Palo here in Texas (simply put, he's a big deal in the tuning world) and I have the utmost confidence in his tuning abilities. I will be running E85. I intend to use the O2 sensor to actively trim while I drive and not just as a readout to let me know when something goes wrong. I've known people who had cars that were great at WOT but they sucked at partial throttle. I want my car to have good transient response.
I would like to build the fuel injection system with scaleability in mind. I don't want to do anything shortsighted and (if it doesn't screw up my time frame) I would not at all be opposed to adding coil-on-plug ignition or a higher resolution crank trigger wheel. In the future, when I want even more power, I would like to more or less be able to add a built engine to the mix, up the boost, and get some additional tuning. In other words, I'd like to build a high-horsepower-capable fuel injection system and I would like a great degree of control over the engine.
I really appreciate any help you guys are willing to give.
