Resize Injectors not working for Z32

Post by d_flore »

Hello, I just installed my DW 740CC injectors. The car starts and runs extremly lean and ruff for about 3 seconds. What am I doing wrong.
1.Click Consult
2.Load base image from ECU
3.Resize Injectors-> Factory CC top and 740 in bottem
4. Click Burn to ECU
5. Says burn is succesful.


Car runs like its still using the 370 tune i think.

You shouldn't need to burn to the ECU unless you know your changes are working

What is your injection multiplier before/after?

Have you tried lowering it to make it even leaner?

Try doing a log with your injection pulsewidth to see what it does during/after starting... what are your AFRs?

I found a small fuel leak where one of my lines was damaged during re installation of the plenum. I don't think this would make it run rich though?

I will check the multiplier once I can turn my car to the on position. I want to replace that fuel line before I prime the fuel lines.

I cant do any logging because the car kinda hardly runs for a few seconds.

My Wideband shows 50 lol so I guess it could be lean but I dont think it would run at all at 50. I smelled fuel but on second thought that could have been the leak.

P.s. this is for a Z32

Is it possible to just get a basic map for a single intake and 740cc injectors to download with a quick step by step to burn it on to my ECU? Sorry for the number of posts I just keep getting ideas?
