Hondata

issue is fixed after forcing the pump clips onto the housing. thank you for the help.

attached is the log, i let it idle for about 15 mins and then drove it, no CEL like earlier. the numbers look better to me but im not positive theyre as close as the stock pump numbers were, i did notice there was points where i was getting more pressure than the ecu was commanding and that never ...

Just want to be sure this is the intended install method because it looks terribly dangerous for my factory housing as the plastic retaining ring is quite badly tweaked and in my opinion is a break waiting to happen. So far the idle log looks virtually identical between difp and difpcmd. Going to ...

I will try to re-assemble it and gently force the clips on tomorrow and see if that gives me more reliable fuel pressure. I will update with a log once I complete the change.

It does turn on when the car is in accessory and its primed. Funny enough just now when I switched the hondata pump with the factory pump and I disconnected the fuel line from the outside of the pump housing barely ANY gas sprayed out or even leaked out unlike when the factory pump was removed the ...

Am I leaving the tune the way it is when I swap in tank pumps? So 1330cc injectors and a trim of 0?

Copy, have checked and there is zero signs of the rubber breaking down and the system is less than 6 months old as are the hoses.

Also having an issue with the hondata fuel system, installed everything to spec and when at idle DIFP and DIFPCMD are damn near identical (within 10 PSI) however after about 7-12 mins of driving i throw a CEL and the pump shoots to 100% duty and i drop to about 40psi for DIFP. Ive attached a couple ...
