Yeah, I've noticed adjustments only "really" need to be made on higher boost and 700+ to the tire setups... Anything eaton based has bad problems - haven't seen anything that bad on whipples or any other setups especially if they're using the stock intake manifold with a centri or turbo - just primarily eaton blowers...
The first one of these I had really bad problems with was a Magnuson Heartbeat at 21psi - actually melted the ground electrode off in cylinder 8... No matter what I tried with injection timing, different rail, injector and regulator setup - still was lean... Wasn't till I started tuning with the individual cyl gains that I fixed the problem...

messed with it a tad last night, pissed the motor off about 4k rpms. Msec spiked and dumped fuel, then flattened out after that. picked up 6 whp by doing it.

Hmm, I haven't had any problems with it that I've seen. Even the Hennessy vehicles I've tuned have been using these tables. Interesting.

Tried this on my ZL1 and did not work. Car has minimal mods: Lungtubes, JLT intake. All I did was enable 'injector gain' then changed values for cyl# B & C to 1.02. At 4000 rpm it cuts out, goes lean and fuel pressure drops to 30 psi for a split second. Any Ideas? It seems like the problem is the fuel pressure dropping.

If this is all you have done then you shouldn't need to adjust anything in regards to fuel pressure or injectors. Just dial in the MAF. You might just have other failing hard components.

that is exactly what the v did while messing with it.

It's most likely just OS to OS issues... I've used this on quite a few now and haven't had problems, BUT here lately it seems like I'm getting a run of OS headaches where I can't fix a problem because I don't have access to the right stuff... Like I've said before every Hennessey vehicle I've gotten in has had this populated and in use...

This is a shop car, so I don't mind posting this one... It's using the injector gain setup - in fact I dialed it back for testing on a pull and lost 15hp, so I know it's beneficial - that wasn't even fully disabled... This is the car in my signature too...

So can you list the OS youve successfully used this on, and guys where it did wacky stuff, can you list your OS so we can build a table of which function properly and which dont. im sure some of the smart guys in here could likely then swap segments in to get the feature working right. its definitely beneficial for the LSA blown cars

Sounds good to me. Is this what you need?
