fuel pump priming at key on

Is there anyway to increase the length the pump primes for in tune at key on?
Not sure if my fuel valve in the tank is dying, or the pump is just meh. But having issues with having enough pressure to feed the injectors after sitting for a bit. If I double prime the pump, no issues. Otherwise it'll catch and die and immediately start on recranking.

Re: TCINJD scalar

Ok think i might understand this?

the CPS is on the exhaust lobe on bank 2 is used as the trigger right?


0 starts the exhaust stroke and its measured in degrees on a circle, so if I had cams withs 334 degrees of exhaust duration, id just punch 334 in the graph?

Re: TCINJD scalar

Yeah im fairly certain that one isnt on my XDF.


If you get a chance I really need to fiddle with it, fairly certain im blowing fuel on my HEGO at idle lol.

Re: TCINJD scalar

Whats the functions name?
Only thing Ive ever found was the offset table.

Re: TCINJD scalar

Would you be willing to elaborate so i can better time injectors to big cams?

Re: Spark map check

Sure, ive since changed it a bit , dang thing rattles like a rattle trap and Ill periodically convince myself its low load ping.

Also figured out the K constant stuff finally lol. Scaled the MAF weird afterwards, but wideband still says its mostly on the money.



Funnily enough, of course a lot of your datalogging stuff started working afterwards, and while the MAF readings seen scaled up quite a bit afterwards (250'ish G/S pre K constant vs 330+ G/S after 30 k constant) versus prior, your ADX's whp math matched what I calculated based off the old unscaled MAF peak #'s

Re: TCINJD scalar

So TCINJD isnt the time constant for injector delay that the offset is added too based on the voltage?

TCINJD scalar

This just says sec as the measurement and does not say the metric in the comments either.


It seems to be set to .5 in most the stuff Ive downloaded from here. Which seems really high for an injector dead time if it is seconds.
