NVRAM 11p tuning discussion thread.

What is yours 304 or 355?

I'd look at a stock 304 tune with the 775 injectors.

304

I’ll have a hunt on the forums tonight and see if I can find a suitable bin to rob

Do you have the memcal ID tool? It should have all the known .bin files and matching .xdf to suit.

He is still 304"
Did blues come on any 5.0's or only stroker models?

Only the strokers.

Found another tune on pcmhacking of a 304 running 775s which was 0.116 so should be pretty right hopefully.

Do a few logs and see if your VE's are way too high or way too low and adjust accordingly.

Post from my build thread:

I have been discussing with @Immortality all week about this 11p tune. We decided early on the issue was my fault for changing the PPR code to correct the ecu speed to match actual gps speed. But this threw the shift points out, and I had not correct the right tables (or enough tables) to sort the issue while at the track.
I wish I had remembered of my error at the track and I would have more aggressively slashed the 2-3 shift point before creeping it back in during the day.
But in the end immortality found that the eco/pwr switch was not switching as it should and has corrected that. So good all around. I just wish I had sorted it a week or a month ago and had a better day racing.

Aaaah the ol ECU speed issue.

I've got a speedo corrector on mine for the 3.7 gears however it's wired in after the ECU so it only corrects the speed on the gauge.

All of my calculations on shift points etc I have to work out in my head.

Glad your trans is in the clear though, that could have got expensive!

Yeah, 'cruise' last night actually showed engine road speed on the data dash almost bang on for my dash display which was cool.
And I am sure I set transmission road speed good to gps speed so when at the track the printed trap speed could be referenced back to the log.
I'll PM you any other details.

Test drove today with VSS at the calculated number for 4L60e/3.45:1diff/25.7"tyres and PPR back down to 40.
That speed reading was bang on for gps (+/-1kph). So I think we will leave it like that and touch over the shift points again at a later date.
