Hi Adam, Looking at getting a G4x for a vr4. Has the latest g4x ecu had the knock pin rectified? Would appreciate some info on how to fix if not. Thanks

Awesome thanks for the info. I will upload my previous tune and give this a try on the weekend.

Ah ok. I just went 7ms - 25% on the cal and got 5.25. But if I go 5.6 + 25% I’m back at 7. Care to help me out with a bit of simple math? Can’t think right now. Must be working it out wrong. But yeah it makes sense with going lean. I have put my new dead times in though.

I have upgraded from id1000 to Bosch 1250 injectors, so a 25% increase. I have decreased the master fuel number by 25% and have been able to drive the car. (7ms - 5.25ms) But as soon as I use a bit of throttle it’s lean. So I have been road tuning but am finding the numbers to be going well over 50 at 100kpa and I’m going to max out the table. what I’d like to know is, is there another or better way to adjust to get very close to original tune? Am I better off leaving the old master fuel number and decreasing the fuel table by 25%?
