My previous 1/4 mile without nitrous was 11.661 @ 117.23mph. So I finally made it to a track event and it was chockers, only got 3 runs in so I couldn't even do any sort of testing. First pass 12.367 @ 111.94mph, bad all round, nitrous never came on? Confused a bit, checked the logging and the AFR was too lean, upped the fuel pressure on the fuel cell from 33psi to 38psi, (using x8, 25N, 15F) I thought it may have been rich enough which is why I set the fuel pressure as low as 33psi to start. I adjusted the AFR cut-out from 11.8 to 12.5 (the AFR fluctuated like a heart monitor). Second pass 11.131 @ 116.93mph, much better, good traction but my 60ft was slower than my previous best of 1.689, which was 1.769 this time round so there is improvement there, changed from 1st to 2nd at 5000rpm instead of 5900rpm, backed off with 50 metres to the finish line as I ran out of rpm/gears (so I thought) hence why the mph was only 116mph. Third and last pass 11.841 @ 122.52mph, bad traction on this lane, 60ft of 2.091, kept my foot flat all the way through the redline. If traction was good then a 10.99 was begging, almost 6mph quicker than the 11.131 pass so there is potential there. All in all the nitrous was smooth and I just need to iron out the AFR and read the plugs which I never did
