I have a d16z6 turbo hatch. running uberdata with p28

fuel cut is set to 7300 but car is fuel cuting at 6100
tryed 2 different ecu's, tryed my friends chip that goes to 7300 on his car but not mine. if I make the fuel cut at 8100 on the program the car will fuel cut at 7000.

im stumped.

Interesting problem. Post up the bin, it could be something stupid in the FTL stuff. I trust the signal coming from the distributor before I would trust the Tach.

I don't understand how you tested all of this? 2 ECU's? 2 chips? please explain better

 

my friend has the close to the same setup and hes using a p28 socketed with uberdata. I tryed using his ecu and chip in my car and the same results . but it works perfect in his car

If you say your chip and ECU wrks in another car then that means it HAS to be something mechanical happening. Spark gap? Check your whole dizzy assembly. Come back when this is done.

 

put a whole new dizzy and same results.

maybe the honda rpm gauge is off?

lol you think? this is a common problem with stock honda tach's they are really far off at high rpm, for example my tach reads 7800rpm at 7300rpm (have shift light set to 7300)

 

Just put a new fuel filter and new spark plugs.

can the rpm diff on the stock cluster be 1500 rpm behind?

 

datalog the rpm signal

 

having trouble datalogging any p28 ecu with uber and the moates hulog usb cable.

it works on a friends p06
