And again thank you VL. Ill use the 60PPR as you suggest. It doesn't have to be GPS accurate but at the moment i am getting over 25km/h error at 100km/h.
On the dyno i was hitting around 200km/h in actual roller speed but the tune was seeing over 255km/h at 5000rpm and cutting out. Now ill be able to do a decent power run up to 8000rpm.

Re: Driveline constant ratio
oh I forgot, I meant 5 speed manual. I don't have any auto cars so I didn't think about that.BARBS wrote:I thought the commodore 4l60e had 0.7:1 overdrive in 4th and 1:1 in 3rd?
Also my problem is not so much the speed cut now as i have fudged it with an incorrect driveline ratio but i am finding my speedo indicated by the ecu is incorrect and making my shift points all over the place.
Ill make up a spreadsheet and work out the errors then adjust my tune as required.
