What's the typical Total Timing for the 2.2 & 2.5?

Much appreciated Kevin!!

kevin,

you wouldn't by any chance have a chart liek that for the fuel settins on a TII 2.2, one that was inercoolerd factory with the garret so like a glh-t or somthing. Showing pulse width and rpm with load...?



thanx

Unfortunately, no. The fuel calculations are a bit more complex and I have to admit I don't quite understand them fully yet. The fact that it isn't exactly well documented like the spark advance doesn't help in that regard.

I forgot to mention that a simple two axis table wouldn't work for showing the fuel because you have three variables (that I know of) -- RPM, MAP, and Air Temp (On a T2).

Ryan,
Have you been back to MIR since you solved your lean problem? Do you still need those humongous injectors now that you can do something with your timing? When is the next Test and Tune"?

I went to MIR 2 weeks ago (10/1) thinking the car was back in the game. Not so. She would lean out up top everytime. Lifted the head again. Like the 8th time. After a hundred different set ups with fuel, timing, spark, boost, octane I narrowed the problem down to be timing. It was as if the knock sensor came alive and pulled a ton of timing out of the car. The EGT's would rise out of control. No matter how much fuel I added even during the pass (using the rich knob). Keep in mind, I run 108 - 112 octane for all of these runs.

I have not ran the car since I've put the ignition control on. I'm very anxious. Even with pure 110 octane, I'm a little unsure of how much total timing I can run. I'm currently running 24 adv total timing at 22-24 psi of boost. No knock . . . yet. The power can really be increased by simply advancing the timing here. But I just don't know how much more I could go. The power/torque already feels incredible. She's got an 11 in her. Just got to get the launch thing mastered with this tight convertor.

I'm planning on running it at the Nov. 7th MIR Import vs Domestic "World Finals".

BTW, No lean condition anymore (on the sreet that is). I am running 72 lb injectors. But I'm making just a bit over 400whp so far. The 53's were gettin maxxed out. Didn't want to risk it. You don't really want to overwork and exceed 80% duty cycle of your injector. In general, 80% for a 53lb injector is about 380hp.
