Is My Tune Safe? Cam C6 LS3

[StockishC6]

I have a Cam and bolt on C6 with the LS3. I have been messing with my tune because it wasnt/isnt correct after paying multiple tuners. I was/am having a lean spike/KR under quick jab Wot, few spark knock here and there while cruising, and it felt slow. I am totally new to tuning and I have read everything I can find to try and fix this. I have made the lean spike better but it is still there to ruin my day lol.

Mods:
-TSP Cam kit, TSP Full exhaust to NPP, yank ss3200

Ive made changes to:
-MAF Curve
-PE EQ
-PE Throttle Hot Enable
-PE Enrichment Rate and Enable kPa
-Spark table on High Oct.
-Transient fuel Impact table(70-100kPa). Going to remove the 1% extra at 70kPa because my idle touches 70 sometimes.
-Spark reduction under TQ Management is disabled as well as spark reduction on power down shift.

All of the other changes were made by various tuners.

My main concern is that I'm going to hurt the engine.

Any suggestions are appreciated even if its that I shouldn't ever touch the tune again lol.

If a better log is needed I can provide that!


Thank you!!new12 PE change, and Transient 70-100 add 1%.hpt3-10-24 Tune 12.hpl

You changed some things for the better. Start by setting the pe enable map kpa to 82, the flatlined eq ratio at 1.18 was fine and the current will not hurt anything. The original spark map seemed aggressive but yours looks on the low side in the low to mid range. Disable discrete shift torque mode in the trans you will be much happier with the shift. Its for sure a step forward from what the read file was. I would recommend some more torque management, set the torque factor back to 1 and use the adder/adder modifier table. Set all adder tables to 1 except the skip shifts.

The PE enable kPa was set at 85 originally, I lowered it trying to get it to come on faster due to the lean spike. I will put it back to 82. I kept pulling timing to try to get rid of random knock at cruise. When entering PE it was hitting 18s afr and knocking. messing with the PE throttle table has helped this knock but not eliminated it and the lean spike is still there and it pulls timing. Is the Discrete shift pulling timing for the shift? Thank you I will try your suggestions out today!

Please post a data log instead of trying to explain what you're seeing.

If you have an aftermarket cam you need to tune your VVE. It'll run, but won't run right, without doing that.

His 1st post has a log. Its spiking to like 18afr on tip in when he goes WOT. Then quickly recovers to commanded.

The log is behind the tune file in the first post. When tuning VVE does my Dynamic airflow need to be active? I believe someone disabled it. I found a good video on histogram setup for tuning VVE but I want to make sure dynamic air isn't involved. Thank you!

Oops. LOL

Honestly this doesn't look great.

The timing table is pretty rough. No VVE tuning. I'd put the transient stuff back although that change you made is pretty insignificant.

As g/cyl goes up the amount of advance you have should always go down. you have a big lump in your table. I can see you hit the interpolate button on it a few times too.

Ive basically tried a bunch of things trying to cure KR with no experience lol. After paying 2 people to tune this thing I figured Id give it a try. It was dyno tuned first and kept dying, second tuner had it running but not as good as it does now(still bad). Hard to find quality work apparently lol.
Is dynamic airflow being disabled stopping me from tuning the VVE correctly? After I get that figured out ill try to clean up the timing table. Thank you for the information!

Last 2 prior posters are both professional tuners that do remote tunes and can get it straightened out.

To tune the VVE you need to have dynamic airflow RPM disable and re enable increased to above what you expect to hit


Goat rope series on youtube helped me a lot.

The biggest thing is to make sure the MAF is failed and setting a code.. even if the light is off.

The dynamic calculation enable/ disable should be put back to stock or higher. But if you have a MAF code that's not going to matter much either way.
