are you running a factory ecu or aftermarket. If you are running the fast system, you can turn the key to the on position (not running) pull up your dashboard and look at the map reading. It should be about 100-104 for a 1 bar map. I would think it would be the same for a 3 bar map since it...

Thanks. I will check into it.

Anyone know of a good place to buy 72# injectors? Looking for a quality matched set if possible. Not just the cheapest price.

It almost sounds like you are hitting a rev limiter. Where do you have the rev limiter settings in the fast box? Do you have an external ignition system with limiter capabilities?

Thanks guys. JDEstill As for changing the VE numbers to get to AFR. This is the first time I have been able to get a full throttle pass. I have never tuned that part of my map. The rest of my map (street driving part) has been tuned to limit O2 correction. Don't see 6900 rpm on the street...

Thanks for the replies. I will do that and let you know what I find. I put the rear back together on Saturday and drove it around a little. but did not pull any logs.

I do have data logs from the 4 runs, but I did not have O2 correction as one of the items it was monitoring. As for fuel pressure, it does seem to be constant. The VE numbers are the same down the length of the run and the AF rations stay fairly consistent (within .3 afr). I am running an...

I finally got my car to the track. Starting making some headway. On the 5th run, split a mini spool in half and ate both axles. What I did learn was that I had VE numbers at 120 to get the car to 13 to 1 AFR. This was with 35 degrees of timing. The duty cycle was 87% at the max rpm(6950). I...

It sounds like a warm up enrichment issue. did you by chance tune the engine while it was still applying warm up enrichment? if it happens when the fan kicks in, that may also be the point at which the system removes all warm up enrichment in your program.

you have mail. good luck.

Ricky, Are you still using the same(or close) GCT you sent me a while back? I am going to go back through that and see if anything jumps out. It is odd. I am running about the same engine combo as you. 383, dart heads, 10:1 compression. The main difference is that I am running...

I have had the same problem recently. I would turn the car off. start it back up and would have running problems. One time I found 3 cells in the VE table that should have been in the mid 80s that had changed to 130. a different time, the car starting idleing high, went into my IAC vs tps screen...

I am pretty sure that a rich pop will come back through the intake. If it pops through the exhaust, I think that is indicative of a lean condition.

I had problems getting mine to connect at first also. It turns out that I had the com port settings wrong. The connection on my computer was using com 1 and my Fast unit was set for com 3 (or vice versa) You may want to check that.

If you start popping out the exhaust when it goes under boost, are you sure you are not going lean?
