1/4 mile track video

One of only two good passes, grinded 4th, should have been a 10 sec pass. I have to figure out these problems with the car. It's fouling plugs very fast but the AFR is where it should be. I have a theory but havent got a chance to test it. These were brand new plugs and it fouled them after only two passes.

1.55 I pulled the 1st plug after that race b/c the car was backfiring down the return lane bad. That one was white like it was REALLY lean. It was too hot to pull any other plugs. I'm thinking that some of the injectors are not firing correctly causing some cylinders to be WAY rich and foul those plugs, and some to be way lean. However on the wideband everything looks good because the lean and rich are canceling each other out by the time it gets to the sensor. I made one more run after that and ran 13.1 @107 full out and seeing 13psi on the gauge so I was running on like 4cyl.

Yea I know, so either some of the injectors are clogged/not working or some of the megasquirt wiring is not correct. Dont know what to check first.

Yea I went through and started soldering all the connections today, ran out of solder though. The ones that were rich and the ones that were lean were on different wire runs so I'm guessing it was a wiring problem. I'm going to solder all the connections though.

What color was your car? I saw a bunch of lt1s, faster than me too, kind of made me wish I was still on spray.
