I have my Hondata boost set relatively low at 15psi and have hit it before without any problems. Yesterday it was a very cool night and I was making 15lbs plus and hit boost cut and my car died and now I am not getting the fuel pump to go on. Swapped pumps, did nothing. Checked fuses...nothing, checked outher misc things everything looks ok. Swapped with a stock ecu just to turn the ignition on and the fuel pump went on? Any idea what happened? Think somehow the program got messed up? I have no clue.

 

what hondata ru using?

didnt have any issues with that. maybe ur pump got busted?

im using s200 its not the pump because i put a brand new one and it still didnt work and it worked after i swapped ecu, i just dont know what happended it has to be ecu related

 

I'd talk to the Hondata guys, they may have run into this before.

Otherwise if you can reburn the chip with your tune on it and see if that fixes it.

 

well looks like its definitely the ecu or the chip i guess, i swaped ecu and the pump primes, how do i go about getting a new chip only?

 

Call the guy that tuned it.He should have the bin. on file and can just burn a copy for you.

 

now someone else is saying that the ecu may be fried and not the chip?

 

did you check the fuel pump relay..had same problem with my car

 

i think if u guys read the whole post u will see that it has to be either the ECU or the chip.

well ended up being my ecu took a ****....if anyone needs a p28 ecu that can fix it with the harness built in already let me know!! 100 shipped
