new #'s put 100% meth in the alky tank and drained the E85. Filled up with 89. Drove 35 miles to make sure all the other was gone.
6000 rpm wot 3rd gear 21.5 boost o2 crr. -5.5 inj 80% 0 knock
5600 rpm wot 2nd all the same but inj at 70% A/F at 11.25 BTW my timing is at 22.5
That E-85 and water had you going the wrong way. Now you need to setup the correction to get you the desired air fuel number. And tune your VE tables for your alky and fuel. There is no problem with 89 octane.
So these are the parameters I typically use.
Timing at WOT 20 degree's
Target AF set to 10.8-11.0 at boost levels above 15 PSI.
Correction limits to +20 and -5
When you do your tuning roll into the throttle and data log the air fuel. Do the same tests all the time. The longer the pull, the better. 3rd gear is best. And look at the data torwards top of third. Get the correction top of third(by adjusting VE) to +-2%. The less.. the better. If your computer says 10.7 air fuel and -5 correction.. then you need to remove 6-7% fuel to get you to 10.8-10.9. This is where the tuning takes place, in the VE fuel table.
Once you have the air fuel squared away, you can then bump up the timing to 21,22,23,24, etc.. as the motor makes more power.
You have another table in your system setup that does "Correction Limits" More than likely than one is set +20, -5. Meaning the FAST will add 20% fuel or subtract -5.. trying to get it to the commanded air fuel number.
When you punch the pedal there are a lot of things going on. Like power enrichment(tps vs ae, MAP vs ae, throttle follower, etc) this can throw off the tuneup. Analogy.. on Holley Carbs there is an accellerator cam that cuases the carb to pump fuel when you crack the blade on it. The fuel injection does the same.
This is why I say roll into the throttle and keep the car at the same boost for an extended period of time.
Hope this helps.
