I understand Arrow claims to have run it with FAST, but it sounds like you, too, have run it with that.We use the MP3 format, so our digital files will play on virtually any computer or audio device. You still have the FAST system, and it did run with that before, but now won't? I'm kind of confused there. Does it have hydraulic lifter that could bleed down? Regardless, I have had engines sit for a lot longer than a month without losing compression from either the cylinder walls being a bit dry or the lifters collapsing. Something seems screwy there, especially since this is a new engine. I assume this is a stock-type sensor mounted to the block such that you can't change its positioning much or even see the wheel? Is it Hall or VR?Įdit2: Hmm. Typos may result in 'garbage in - garbage out' from both us humans and the MS ECU.Įdit: Alas, the tooth log posted show so many 'missing teeth' that I can't even guess what kind of crank wheel that is. I don't mean to be an ass about that, but urge you to be more precise in typing. If anyone has insight as to why the engine wont start it would be much appreciated!Īgain, is that a typo? I see no '36-2 -2' option in the spark-mode menu. The old FAST thread is here with more details and pics of my car: I like the MS3 as it has a much cleaner wiring harness and datalogging the crank & cam sensors I previously had a FAST XFI system on the car. Wideband o2: Bosch LSU4 0v= 8AFR, 5v= 18AFR I am unsure of what my reluctor wheel pattern is inside the engine? Regulator is set to 52 psiĬrank pattern: 36+2+2. Injectors: 42lbs/441cc There is fuel to the injectors verified by pulling all 16 spark plugs which are wet covered in fuel. MAP when not cranking: 99 kpa (verified no vacuum leaks) I did almost all of the installation myself. It was test run with a FAST XFI system at Arrow Racing and then shipped to me. I also have the trigger and sync error logs and can attach them later.Įngine: is a brand new 426 aluminum Gen 3 Hemi crate engine from Arrow Racing in Michigan.īasically a 6.1 Hemi engine with stock coils and a late 5.7 plastic intake I have attached the tune inside the MS3 and also the tooth log.

The crank and cam are not syncing and thus cannot fire the engine. I have been helped out by a few friends online and they were able to see that I have a sync loss issue. I am posting up on this forum for help on trying to start my Gen 3 Hemi crate engine.Īdmittedly I have almost zero knowledge of EFI as my previous engine was carburated.
