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%?
