Hello everyone. I recently picked up a B20 swapped 91 Integra from my friend and it came with S300 installed. Car should be lots of fun once I get it tuned and running correctly. A little about myself, I am a technician for Chevrolet, ASE Master certified and GM World Class so I know my way around a vehicle. However this tuning software for this platform seems rather weird to me. I have lots of experience with Megasquirt/Tuner Studio, Haltech, AEM, HPTuners and Cobb but for the life of me I cannot figure out some issues with Hondata.
First thing is this car has a turbo on it. Cool. Anyways It is running lean in boost. I'm seeing 13-13.5 at part throttle even trying to get into boost and I can tell its breaking up most likely due to the lean condition. I don't even want to go WOT until I can get the tip in/accel enrichment right.
On the target lambda tables it goes from 14.7 to 13.5 to 12.5 and it will not allow me to adjust the specific cell numbers. I can use the + or - button to change the 3D graph up/down but the value within the cell does not change. Is there something I am missing here? I have attempted to use the Adjust function and specifically type in the desired numbers but the cell will still not change.
According to my friend he had the turbo on the car and had it street tuned ok, but then later installed some upgraded camshafts and it requires a retune. Shouldn't be anything too crazy. I just want this thing to get rich first so I can lean it back out later. I have yet to go over the engine to ensure that there isn't a mechanical reason behind this issue. I am sure there might be.
The other issue is the row and column values. Is the top row in bar or vac/psi? Is there any option to convert these numbers? The ignition table he has shows 22 degrees of timing up top which to me is insane unless there is some form of correction factor and the ignition table I am looking at is a base table.
Last thing is the primary/secondary tables. What specifically is the referencing for those? Do I only tune off of primary or is it a mix of both?
Thank you for any help or advice you can give.
