Something odd here. when i change to my settings for the new injectors and compensate AHISL for SP** i get a no prime no crank condition .

Any reason this happens . my old was 57lb/hr the new is 74lb/hr . K factor is at 30 as it should be and a compare shows that not much is changed except checksums and MAF etc.

im chasing an issue where around 4200 RPM the ECU seems to reset or something.

This is a log that caught that even at WOT .

Old injectors were causing fuse 19 to blow. but this issue i see now i was experiencing prior to that .

I need to do PPRV delete i suspect as its causing low fuel pressure and higher duty cycle due to restriction . Just trying to source the issue here over all . Running the old program for no which runs but this one with changes to high slope wont even crank . and changing high slope alone causes no crank conditions.

that means your using an outdated dma datalogging patch and causing it to corrupt

How do i update the DMA patch ? I thought it was the latest one .

i will also note the resetting issue is intermittent also. sometimes i can pull to the moon and things run great. other times the car konks out for a split second. like a rev limiter.


On the data log itself it looks like the ECM restarted or lost power idk . tracing Fuse 19 i dont find any loss of power on that circuit. the issue is horribly intermittent though . In this log it happens around 951 frame .

Not sure if these issues are co related or what.

its looks like the tune is corrupted, no doubt the datalogging is

you need to download the latest rzasa adx and xdf and remove then enable the datalogging patch then you can enter in your injector high slope

Will do. Thanks !

Do you have the latest ADX ? I believe i may have an interchange where i had a newer version than released when i was dealing with the OBD2 P1000 self check issue. I didn't see it anymore. i believe it was like 28xxx . Currently using the ADX and XDF from the main thread under RZASA .

When i update the injector high slope do i have to re enter the old MAF , SARCHG , offset values again like the initial procedure for the K ?
