AVCS - Intake and Exhaust Timing

Map 01 has the most power overall but a little too jumpy while cruising.

Map 05 had the smoothest downshift between 4-6k and was also the most linear map but lacked the top end power map 01 had. cruising was very easy.

Map 04 was a combination of the two.

Take a look at the maps and come to your own conclusion... im actually gonna combine both 01 and 05. ill use 01 maps from .85 and up and 05 from .8 down. Ill let you know how that goes.

however only the dyno will tell....

It's a little too soon to start mixing maps yet. The first step is to find the tune that starts making more noise than power. I sent you three more tunes, from 06 to 08, to try out as well. Those should be progressively worse. Let me know if they seem to get better as you go higher from 06 through 08.

The only difference between them are the AVCS tables. I'm currently using the one equivalent to the 03 tune. You have 2 tunes with less valve overlap, and 2 tunes with more overlap than the overlap in tune 03. Load all 5 tunes in your OFT and try them all. Keep the one with the best power. If the best one is tune 01, or 05, than send me a PM for more tunes.

This is tuning by trial and error one digit at a time. You'd be surprised how different even 1 degree of change feels.

Quoting this because I have local access to E85 and a dyno tuner, suggestions on which one of the tables might pair best with the UEL OFH?

Use the last ones KoolBRZ put up I have a jdl uel header and it works great.

Is your CAL ID A01C? If not, tell me your CAL ID and I'll make you a set. Right now I'm still trying to get the AVCS Intake and Exhaust spacing correct, so I don't have a good starting tune for E85 yet. The more people who work with these tunes, the faster I can come up with a universal starting tune for E85. A starting tune is close, but not perfect. The starting tune has all the large changes made, so that only small changes remain to perfect it to suit each individual car.

from read this . ots is best(for the time) for NA engines .

spend days reading and reading this thread
maybe I will do same my own AVCS changes and have same experience on it

Where are the dyno result then ? Should we back to shiv..? He is the one with proven dyno sheets
