Whelp, no turning back now.

I submitted my proposal for my senior design project, looks like I need to step up to the plate, and commit to making this damn thing. The overall goal is to make a custom, super affordable, programmable ECU for our cars. The goal by Late April / May is to get the car to start and idle.

Ive been doing TONS of research on this so now its time to get the ball rolling, wish me luck, ill try to keep you guys updated if I have time. Id love any suggestions / feedback as im going as well.

GL with it man. Mechanical Engineering or Electrical?

[x2percentmilk]

Computer Engineering w/ Computer Science minor, but I cant even count how many electrical engineering credits ive taken.

will this benefit 2nd gens or just 1g guys? either way good luck

[GTOJOE]

how affordable is super affordable?

[x2percentmilk]

400-600 dollars, depending on how things work out. When its all done it should work for any 3/s, though you'll need the separate CAM/CAS sensors of the 93+, and maybe some other small details ill find out later. Im hoping to even allow you to run this while leaving the stock ECU in place for OBD, if you care/need to. If its commercially viable ill also have a neat dash accessory for it and some other fun stuff, but thats looking into the future.

FYI the 91-92 CAS and 93+ CAS are directly interchangable. The signals are derived the same way. The ECU doesn't know the difference. There is only a minor difference in latency between the two styles.

I had a guy buy a 95 NA Fed Spec ECU and drop it into his 92 with no problems.

so you're going to do what gatecrasher never finished?

easily worth $600, assuming:

1. it's reliable
2. it's pre-mapped for stock

biggest drawback of AEM is the amount of tuning required. if we can get good maps for this, it should really get this platform moving.

[HLxDrummer]

Are you talking piggyback or standalone? If standalone for that price and it works very well I would definitely buy. Even if it was similar to a stock flash-able ECU I'd be down!

If you need any help or need a test subject hit me up

[Austin@STM]

That price should be very doable, AEM could do that price very easily, im sure there isnt much money at all into building an EMS, they are just charging for there research and time involved, oh and to make a ton of money.
