Did a bit of tuning and driving tonight. Logging of course. Ambient at about 75. Bumped timing up to 22*. Worked with the AFR. Thru first and second pretty much 11.5 - 11.8. When it drops into 3rd is goes rich at 10.5. Don't know how I can tune around this. Hopefully the extra fuel at bottom of 3rd is in my max torque range. Didn't have enough road or ***** to wind out 3rd to see what it went AFR wise on the top end. Also noticed that I'm only getting about 7psi boost through second. Had been 9psi. Jumps back to 9-10 psi when it hits 3rd. I changed belt back to the Gates from a Gatorback after reading a few posts about it being a better belt for slip? I'll swap it back and see.

Here is a shot of the start of a launch from first. Stalled about 2400 rpm. IAT @ 122. 16* Advanced. Launched hard. Turned over the front tires a couple turns.

Here is a shot of log at end of 1st gear. I have never seen 21* timing. No KR. IAT 126 and pulling .5 timing. Strange that base advance was at 20.8. Think it means something was adding timing above the base table?

Didn't run into a spot where I could go from dead stop thru second gear. Here is a shot of a kick from about 40mph so it wouldn't drop to 1st. No KR. 22* advance IAT @ 111. Pulled STRONG.

Here is shot at the end of 2nd gear. NO KR. IAT@133 and pulling 1.1* due to it. Before the Alky injection I would normally be in about the 14* timing range here due to IAT and occasional KR.


I didn't try any more timing. Don't know if I will. Pulls great here. Does suck down the ALKY though. With any long pulls I will go through about 2 gallon per tank of gas.

 

I have the same problem as you do, When I am sprying meth My A/R is 11.5 through 1st and 2nd and as soon as it hits third it will go rich (10.5) all the way to 130 mph. and that is with my fuel pressure dropping to 53 PSI

 

You might want to look at your PE table at those low RPM's your at in 3rd gear, it may be your comanding to much PE fuel at the lower RPM's.

I used the PE table and the IAT PE table to adjust my WOT fueling at all temps and rpm's, my AFR's are at 11.3 to 11.6 at any rpm, gear, or IAT.

BTW I have the Snow Performance stage 2 variable controler MAF kit,
it's great with these RADIX blowers that come up to max boost as soon as you hit the throttle because this Snow kit increases ALKY flow with MAF air- flow (Hz) even thou the boost stays the same as RPM increases.

 

I changed jets in my alky injection last night and did a couple of logs. It fixed my high IAT but they look like $hit. Looks like I get to start over with my tune.

 

It is a a never ending circle. Do something, and have to change 3 others. WHY DO WE DO IT?

 

This is my moto:
(IF IT AIN'T BROKE MAKE IT FASTER, MUCH FASTER)

 

Haaaaa, I love it. Sums it up for me anyway.

 

 

For the more rich mixture in 3rd - Is catalytic converter protection off?

 

Can you please explain what that is, I have never heard of that before
Thanks
Mark
