Such a great conservationist, environmentalist, and wildlife educator. He will be sadly missed. He was doing such a great job to bridge the gap between the natural world and the human world. My...

Could you elaborate more on the changes you're making in the Bias table for complex cylinder charge? I have used the Ideal Gas Law and for sure other variables are being used as the IGL alone does...

After logging idle desired airflow, for each temperature, do you plug in the max value seen or the average or the lowest?
After logging (P/N cold startup), the data indicates I need to lower the...

What is considered a significant difference that would warrant changing the MAF table? Depending on rpm, I see a difference between MAF (lb/min) and dynamic airflow (lb/min) of zero to 0.90. For the...

I have a 224/228 cam and the targeted idle rpm in gear is set to 770 with A/C on. Lower your idle rpm with A/C "on", and AC "off" for that matter.

Ok, I'll use that method. I'm running NA. Currently, I have the LTFT's at +/- 8. I logged the STFT's yesterday seeing anywhere from -15 to 2 (no MAF). I need to log more data and hone my driving...

Thanks EC, as always. Hopefully, the weather will cooperate today and I can log some data/runs. I'm trying to tune in similar weather conditions. After researching all of the tuning docs, I'm not...

I've been trying for 2 months to get cold startup issues resolved ie idle hunting for a few seconds until it stabilizes. Just now, I was going to do some VE tuning, set MAF Fail Frequency to "0", no...

I figured a good look at the dynamic airlfow was in order, as this is really about PID and control mechanics. Apart from raising the dynamic airlfow MAP boundaries in line with my DFCO settings,...

Triggered DTC PO751 1-2 Shift Solenoid with these changes. hmm.. Guess I will go back to stock.

Foot out of it? Look at the RPMs and % throttle! I was steady cruising at 60 mph and < 2000 rpm.

Here is the first attempt with custom PID for mpg.

I'll try to post a log today. My bad, it was "0" at idle. LOL.

I tried this yesterday and I'm getting 14.1 at 60 mph cruising steady on interstate assuming I did everything correctly. 5.9 mpg at idle. Does this sound right?
This would explain my poor gas...

Derby City or Louisville KY. I grew up in Bowling Green KY, lived about 2 miles from Beech Bend Park. I did a lot of drag racing on Friday nights and got to see the big boys/girls like Glidden,...

Good question, I was trying to figure this out myself. I have seen tunes that disable the abuse mode, then rpm set at 7,000, TPS set to 100%, speed set to 255 mph. If abuse mode calcs are ignored...

Would 100% TCC max duty cycle and 90% TCC min duty cycle be ok to use on a '98 Z28?

Ditto!! Awesome product, from Day 1 never had one problem whatsoever. Also, I would be SOL without this forum. The help, hints, tips, etc. is GREATLY appreciated from the more experienced tuners.

Increasing the misfire threshold values helped in my case. Changing to a 98% minimum TCC duty cycle did not work in my '98 with no other changes to the tune. Not sure if its a 1998 thing or not but...

WAD -Working as Designed. Absolutely normal. Switching rich/lean.

I have the same problem. Starts bucking on decel from 40 mph->35 mph. I can't tell if its timing or fuel. It started after cam install.

Well, Adaptive Idle Startup PID delay set to "0" seconds did not work. Back to the drawing board. :)

Thanks guys for your help. I'll try the Adaptive Idle Startup PID delay set to "0" seconds.
Just to clarify, are you saying to change the Base Idle spark "In Park" to the values in Base Spark "In...

Soundengineer, Idle Spark Advance-> 27-28* in "In Park" or "In Drive"?

Under the Idle RPM Tab, on my '98 I see Proportional->Enable RPM Error which is set at 60 rpm. And I see Integral->Enable RPM...

MNR-O, I really appreciate you sharing this method to improve idle, gas mileage, etc. and your subsequent replies to our questions. Some of the suggestions in this method/procedure I incorporated in...
