dump and reload firmwere = same crap results .
restart unit from scratch and new wizard setup = same crap results .

i hear ya ,get my exhaust parts and my handheld goes white can't check anything and there supposed to send me a new on if this thing craps out will put carb on it and go on...........
update email from holley tech dept :
After watching the videos you provided I would recommend to send the handheld in to my attention to be inspected. It appears to be an issue with the handheld itself. If you would please ship the handheld to us .
looks like all my hard work / time spent / bull crap i went threw has maybe paid off . . . .

Hope they get it straightened out for
I was debating about disconnecting the handheld once it's all setup. I was thinking maybe it's better not to obsess over all the details I mean any other vehicle doesn't tell you TPS, IAC, AFR, etc. Assuming it seems to be running good.
It would be nice if you lived near someone else with a Sniper because you could try swapping handhelds.

Yea, you need a new handheld. Touchscreen issues don’t usually improve over time.
I'm sorry you are having trouble with this system. I have a tried and replaced several aftermarket efi systems over the years, each time swearing I'll not do it again. Hopefully the aftermarket will reach a parity with factory reliability at some point in the near future.
some more new info from the holley tech forum .
looks like lots of guys having problems with emi / rfi feedback on the system from dirty 12 volt key hot/crank feed point . the fix for this a few guys have done is key hot/crank feed to relay trigger . then stright batt conection feeding the relay and out to the 12 volt power feed line to the sniper so there is no feedback dirty signal power . seems stupid but 1 guy has done 6+ install jobs and to verify it he did not do a relay on #4 and #5 and had problems so he added a relay and no more problems.
seems holley did NOT do there job on design and testing of these units . .

Eastbound and Down
Fast EFI is very clear you need clean power.
Holley has a whole video about it too, but it's more geared towards the battery power not the keyed ignition power.
sniper is stalling out on me and i have no way to data log it or see what going on with my controller out for service .

That's what sucks, I have same issue. With my Fitech.....
I'd be too chicken to drive mine without the handheld. Do you have fuel pressure gauge?
yep shows 58 - 60 psi . in front of me the whole time left gauge .
I need one of them. Actually I have one; I need to get it installed.
