 |
|
Hey guys. I just tuned a chip to run on my jap ca18det. I have
444cc gtr injectors
t28 ball bearing
walbro pump
rb20 afm
ca16de intake camshaft
the car starts and idles fine but when I put any load onto the motor above 3000rpm in 2nd or 3rd the car will just stumble and then stall. I have made two tunes and they both do this. Could someone tell me if there is anything wrong with my tune or if its just a bad afm that i got. Both tunes are attached. Tune 2 works better on my car.
Tune 1

Hi!
I think that your problem is a bad fuel pump... your first bin don't have the right AFM scale and in your second bin the K number is way way to high...
You could try this bin :

But I'm sure your prioritary problem is not the bin... |

| cool thanks for the file. Its defiantly not the fuel pump because its only two months old and it runs fine with the stock map. |

In neutral position : does the engine rev past 3000tr/min?
PS: Excuse my english... |
