Doesn't Uberteg do that stuff? Is he still around here? I know he is selling those things like crazy on Honda-tech. I don't believe he can chip OBD2 though.

Maybe I am not understanding this whole situation. Ok, lets say his timing is advanced 10 degrees with the S-AFC. His BTM is set for 3 degrees retard per pound of boost. Then at 4 psi he would be 2 degrees more retarded than when not under boost. Why wouldn't this work? Is it because of the AFC still? I'm confused as to why you say this won't work. You can still turn the retard up more per pound of boost and that would not affect anything while not under boost.

Ya you are not quite grasping it the problem is not while under boost the problem is that the AFC hack is rumored to ADVANCE the timing at IDLE, NO BOOST. The BTM retards timing based on boost. I think this is not that big of problem but i have seen someone post that it is at least one worth mentioning. I hope you see what i am talking about now. THanks for having the patience to help me out man! Ya if i had obd1 it would be no problem.

I think im with dr. boost on this one... whats wrong with advanced timing at idle under no boost? besides maybe a lopy idle?

www.batronix.com has info on eeprom burners, I don't know anything about it. and the afc has to keep upping the trickery of the map sensor, so it keeps upping the timing, and the btm wouldn't compensate enough in my understanding, but I don't know from experience, just what I think.

Anton maybe you should read first ..but a BTM will not retard timing at idle. I am not as worried about timing under boost but as honda16hb said even then sometimes btm is not good enough. I realize that my best option is chipping bu since i am OBd2 i will be pressed to find a way to chip mine.

Dr.Boost

Ahhhhh, ok, but why are you worried about timing at idle? It won't harm anything. It might even make your car run better and get better gas mileage. Turn the btm to 3 degrees per pound and your set.

Yeah they are on ebay. $41 right now. I would talk to Rolla1990 for a deal. You will still need an injector box though. Probably around $25.

From what i have heard the afc advances your timing all the way to redline. The btm reduces the advancing when it sees boost but only a max of 3 deg. That still leaves the timing advanced 6 to 7 degrees and i thought that when you boost you want to retard the timing. (that is what the btm is really supposed to do not just fix the afc) I think that is correct. So that still leaves with 7deg of advanced timing which is not good. I was wondering if you can retard the timing with the distrubutor? If anybody can correct me please do.
