Few problems with a 6bolt in a 2g

[beansblacktsi]

Well Im posting this for my buddy. He bought a 95 eclipse GSX with a 6bolt in her but the car didnt run. It has the conversion wiring kit on it and two of the plugs were switched around. So we got it to start but it would barely idle but it did idle. But when you give it any gas at all over quarter throttle it just revs straight to 4k to 4.5k until you shut the car off. We tried running the car with the MAFT unplugged and it idles actually alot better. So we got a different MAFT and plugged it in and it did the same thing the last one did. DOes anybody have any idea what it might be? Did we get another bad MAFT? Any help is appreciated!
Thanks Beans

let me ask this... when its revving to 4.5k are you guys still holding the accelerator down? I mean think about it.. there is absolutely no load on the engine and by revving or giving it throttle of course its going to rev that high. I need some more info though to help diagnose your problem..

also if it has the 6bolt in it they had to change the cam angle sensor from a 2g to a 1g that is why the plug wires were switched so that they did not have to switch them around on the ECU pinouts. I am also guessing this is why your buddies car is missing. The firing order is 4123;however, if it is was switched which it seems like it, then the firing order will be:

The spark coil signal is inverted. Looking at the coils, label each wire A,B,C,D. Change the spark plug wire locations: A is now C, B is now D, C is now A and D is now B. Another way to do this is to change the trigger wires to the coil, (3 wire triangle plug, next to the igniter). Switch the two blue wires. One is blue with red stripe, the other is blue with black stripe. The third wire that remains unchanged is black with white stripe.

I second this, make sure all the wiring is correct, I realize you said in the original post you had the wiring done but it doesnt hurt to go back and check it again! I once had a vaccum leak and I remember checking every single possible spot a leak would be coming from but I never could find it. I was just about ready to give up until I went back and checked again and there it was, a torn vaccum line I somehow missed the first time. Doesnt have anything to do with wiring, but it shows that double checking wouldn't hurt.

I don't know if you researched it so let me just go ahead and say it, when you swap a 6 bolt into a 2g the 2g ECU reads all kind of random misfires which obviously would cause your motor not to run properly. I have no idea if this causes your revving problem but I'm pretty sure it might have something to do with it. There are ways to make the ECU ignore the random misfires and the only ways I know are either to get a chip from DSMChips.com, or just get DSMLink. I believe that the random misfires happen because the 2g has a lot of sensors the 1g did not have, so when the computer looks for it, its not there. Since its a 95 you already have an Eprom ecu so your in luck if you decide to get a chip or link to help solve your problems.

Hope I got you 1 step closer to solving this.
