2g w/6bolt AFC tunin w/rm

[kevingst]

I did the swap about a year ago. Immediately I had random misfire. I did the tps fix. It worked/works , no more rm. I can build cars all day long. But I'll be the first to admit that when it comes to "tuning" these cars I'm stupid. Here's part of my confusion. Doesn't the SAFC rely a lot on the throttle position to make its adjustments? Because I'm boosting 18-20 psi and getting crazy fuel cut. No matter what I do with the AFC, I still get f.c. Now, I realize my stock injectors are more than surely past 100%. But would it really do any good to get bigger injectors? Is my afc actually doing its job? I've got the money sitting in paypal right now that I was gonna buy pocketlogger with, but what use is that really to me? It's doesn't check injector duty cycles/pulse width or knock on 2gs. I can't get my throttle position. Maybe it can give me my HI and LO trims, but what good are those if the AFC is working properly? It'll give me O2 voltages; great...afc already does that. So pretty much I need new injectors and then either A) spend $8-900 on dsmlink and a laptop or B) spend roughly $500 on a Maft setup with pipes. Let me add that I don't have the money for either right now. This sucks. I need to be faster but this lack of money really seems to be slowing me down. Anyway, let me know if I'm right about the AFC and what you guys think

With an AFC and the TPS removed you can only tune the Lo settings because you will not have any TPS input to switch over to the Hi map. Get a DSMlink if you can afford it. I had the same problem a year ago.

Thanks Ezzard. That's pretty much the response I was looking for. I just ordered a laptop so now I just need to save up for Dsmlink and get the time to send in my Ecu. Btw, glad to see your car coming along so nicely since your swap

kevingst, when you did your swap, did you get a 'real' misfire and CEL or was it just a CEL and no actual misfire? Did you rewire the injector wires at the ECU like RRE recommends?

18-20 psi with stock injectors ? Are you trying to blow up your motor? You sure are getting bad fuel cut . I cant run that with all my mods and my fuel pressure at 50 psi . You also live in California where I would say that you are running on 91 octane . Turn down the boost or sell your car before it blows up. :thumbdown

Yes, I switched injector wires. If by "real" misfire, you're talking about when the ecu cuts out cylinders and sends the car into gimp mode...then yes, I have "real" misfire. I don't think I would've allowed myself to drive the car like this for a year if I hadn't known that it was real.

Are you serious?! I'm getting bad fuel cut?! I believe I covered that already in my first post, and yes...on stock injectors. Please don't be redundant. I've seen these cars running 20psi on stock injectors, but that's irrelevant. I don't have much choice. Since I put on the downpipe that's just what it boosts, I've got the controller turned all the way down. But I appreciate suggestion to sell my car. Really, I'm gonna go right out and do that! :thumbdown If you have no pertinent information to add, then why even bother to post?
