A washed-up, loud-mouthed old man who knows nothing about computers teams up with a fresh-faced, wise-*** kid who drives a 5.0 86 Mustang 5 speed with a Holley and they thrash out a totally STOCK, Stock Eliminator car! Wow, a STOCK car in STOCK Eliminator! What a concept! Sounds like a plot for a hit TV show.

Re: Not for Nuthin' But Close!
As with a street car with drivability issues there could be some of the same problems with your car. Sweep testing sensors with a meter could see glitches with your hundred thousand mileage plus car. We have seen small problems with map, tp sensor and knock sensor on the wheel dyno. I will tell you peek HP and torque are at 5500 and drop off big after 6000 due to the intake manifold. Also if you have not pulled the flex off the exhaust manifold you will see that it has a reversion cone at that connection. For some reason this motors do not like much timing. Tom

Re: Not for Nuthin' But Close!
Doug and I went to Cecil Co. yesterday for what will probably (not definitely) be our last T&T for the year. There was a good crowd but it wasn't packed and we made 7 runs. Doug tried a bit more timing and it didn't seem to like it so he concentrated on trying to take fuel out. He did switch it over to open loop to start removing fuel. Now, he was taking fuel out just a little bit at a time but the car kept responding. First 3 passes with the air getting warmer and the baro. going down were;
First pass, 15.262 @ 88.23 2nd pass, 15.250 @ 88.73 3rd pass, 15.221 @ 88 90 Doug had to raise the RPM limiter again as the car started bumping into it on the 1-2 shift (more on THAT later). 4th pass, 15.164 @ 89.10 !!! 5th pass, 15.159 @ 89.31 !!! Now just a little something about the 5th pass, that just happened to be the ONLY pass that Doug has taken in the car. Oh, did I mention that he had a .020 light? Darned punk kids have no respect for their elders...... 6th pass, 15.188 @ 89.11 Last pass, really spun the tires, 15.268 @ 89.11. Doug brought home my laptop to see if he can post some graphs, he said that I didn't need it anyway. Hmmmm. Now about the torque management nannys, Doug DID turn them off BUT we are going to have to find some kind of a happy medium between them being completely off and making adjustments to the line pressure graphs. With the torque management off and the line pressure left alone, the trans starts "sliding" into gear instead of crisply shifting. But that's for next time.

Re: Not for Nuthin' But Close!
Attached is a picture of the main spark table. I only felt the need to modify it from 60 kPa to 100 being that once you go to full throttle the map sensor reads between 98-100. I pretty much copied this table for both high and low octane mode so there is no way the car can change it. The other thing I did was modify the minimum timing table to have a minimum 29 degrees of advance throughout the rpm range. If there are any other tables anyone would like to see, I'll gladly post them on here.

Re: Not for Nuthin' But Close!
where do you find the minimum timing table
