Just changed injectors, leaning out now.
 
I just swapped out my stock 1.6 injectors for mazda b2600 pickup injectors. what I have read on the injectors is that they are 270cc injectors @ 2.25 bar. I did the calculations for the injectors for 3 bar at got 311cc. I entered the info in TS under basic settings>engine constants and got a required fuel of 8.6. now with the same map I had with the stock 1.6 injectors, which was dialed in to my liking, I am leaning out terribly across the map. Shouldn't the map be relatively the same and only need minor adjustments?

IIRC those (if gray) are 320cc. So req_fuel should have only been reduced by 30%.

However, if your injecotrs are now yellow...req_fuel should stay the same as they are still ~230cc.

REQ_FUEL was at 13.4, so 15% IS 2.01. I'll try reducing it to 11.4 and see what happens. Thanks again!
