i dunno about haltec, but on mine there is a decell enrichment. I have mine set to cut the injectors back on at 1800rpm. I found 6% enrichment was a good value to use to minimize stalling. Too much or too little fuel will make your car sputter or stall when you come to a stop before it regains idle. This is specific to electromotive however, i dunno how this applies to haltec

Kind of hard to test this, dont you think?
At idle, the timing signal from all coils is strong, and right on time. How would you test the coils under load? I almost had an engine fire due to a power wire that rubbed though and started arcing on the power steering pulley. You would normally think I would lose spark altogether (randomly as it shorted out), but it starting detonating like a bastard and my tach kept dropping then pegging 8K, that was initially why I pulled over! |
I can definately swap them, ive got more in my parts bins... https://www.nopistons.com/forums/pub...IR#>/smile.png

Nope TACH is solid.
I can monitor the voltages though.. Not a problem, except for the fact that I cant keep road testing it for a ping! I gotta do a bunch of mods at once, and go out and see if it got fixed. Its already been pinged about 5 or 6 times, HARD. I am getting really nervous about keeping it up. So I am going to wait till the weekend when the new injectors are installed, and the FPR is in.

Your very likely maxing your primary injectors and running lean. Having 720 secondaries does nothing below 3800rpm.
|
Which at present is the theory I am going on... But I am always open to more suggestions.
The Blitz 700 cc primaries should be here this weekend, and as previously stated, the AEM FPR is already here. Jarrett |
But you should know better than to run upgraded injectors on a 15 yr old fuel pressure regulator! https://www.nopistons.com/forums/pub...1047683664.gif The stock FPR sometimes getts too weak to support the stock injectors. I personally dont think its a coincidence that your engine pings as soon as the 720's come on. But at the same time this isnt the first time you heard this from me.
