NOT able to get car to respond to changes..

I have a car I am tuning,obd0-obd1 b-16 turbo, I am able to tune the car with 310cc injectors but as soon as I put anything else in 750cc, 1000cc the car does not respond to the changes, you can lean it out richen it up and nothing changes on the A/F, and no its not my wideband, I have tried 4 of them, and I have tried 3 ecu's and 4 sets of injectors..
any help would be, nice thank you..

Are you using a resistor box?

on the 1000cc injectors I am using one, on the 750cc and 310c I am not using one..

Are you sure you have realtime update checked?

I mention having that problem on another post, i do changes on the fuel maps, save it, upload it and datalog it again and it keeps asking for the same values.
I then downloaded the map from the ecu and confirmed it isnt saving the changes.
Its not a soldering problem as i tested changing the 2step to a different rpm and it works.

Set the revlimit to 2500 rpm and upload the calibratoin. Does it take this new Rev limit?

yes it does accept the new rev limiter

open loop or closed loop?

this was tested on open loop

Large injectors have a lot of dead time at low rpm and low duty cycle. You may have to make changes in huge increments to actually see changes. Try a 50% change (ctrl-J).
