What did you do today to your 3/S?

What's your AFR look like? Too rich and e85 will "misfire" easily.

Oh and in the spirit of the thread...MTC received my turbos to be looked over and I sent my FIC 1350s out to be cleaned and flowed. Last things that haven't been double checked on my build.

Low loads around 1-3k rpms it's around 14s high 13s AFR. The only time it went into 11s was when I would let off the throttle and put it in neutral. I have an open atmosphere BOV causing rich shifts. After a few seconds it returns to high 14s idle.

I swapped back to the projected tip plugs I was running and it made no difference. I didn't have time to mess with anything else. I'm beginning to think that while the ARC-2 can handle the fuel control between it and the computer the signal just won't work. Timing is advanced a 2-3 degrees more based off the high octane timing map on a 99 VR-4 ECU so I don't think that's the problem. I will try swapping more ignition components later and a few other things. This didn't happen until the plugs and injectors were swapped. I already ruled out the former so I'm pretty sure a better engine management is needed. I better finish up my ECU adapter harness. Been too lazy. Haha.

So your ditching the arc2??

So your ditching the arc2??

I had planned on doing it eventually. It's super easy to tune but you can still tell it is a modded car with the way it drives. I know you can get one to feel more like stock until you go WOT. Plus I knew that wanting to run ethanol I was going to have to switch. I'm just not big on w/m injection when I won't safely run more than 3-5 psi over pump which our 91 here sucks anyways. I was just experimenting with the ARC-2 since it was quick to do instead of spending hours and hours dialing in a tune before making major changes.

I thought about keeping the ARC-2 for the bigger MAF and zero it out to use in conjunction with the flashed ECU. Air temp is fixed and I thought there was something else when I was reviewing the logs. I will have to ask Greg how much some of those data measurements are used in the calculations of the various things in the ECU because it could throw things off. I have an Evo MAF just need a filter and filter adapter. The flashed ECU is the better way to go honestly. It makes a nice option inbetween a piggyback and standalone. I don't have the time right now to learn how to tune an AEM EMS from scratch but it is on my bucket list one of these days.

I hear ya man. The only reason I went that way was because I didn't want meth injection either lol. To much can go wrong with that I think.how hard is it to tune the flashed ecu deal and whatsit the price? I know someone was selling the harnesses here somewhere.

Will post dyno sheet once i get them. I asked chris about then today he said once everything id back in order they will send them

LOL'z I know what someone was doing in Mexico yesterday....

Not my car but I figured I'd share what 3S relate stuff I did.





It's to match the half snakeskin green paint job. Should look awesome once I have the valve cover and calipers done too.

[IPD]

nice! i think i prefer the stealth look though.

Made a for sale thread, then looked at car and closed for sale thread on other forum.
I don't understand why I always remember the crappy parts of my cars but never the nice parts. My blue car, I could tell you where every scratch and ding was in that thing. My white car, same thing....frustrating....
