Do you have some data sheet for the new injectors?
If you have ls1 style injector data you can try my newest patch.
What is that lt4 bin you have? As far as I know lt4 was introduced 1996.

Hm, only the usual...
Static flow @ 3, 3.5 and 4 bar
Dyn flow 50% duty, 3000 pulse/min 10ms ' 3 bar
Dyn flow Idle duty, 800 pulse/min 1.5ms @ 3 bar
And a list of Dead times (Latency) - Voltage vs ms
So far the VE tables are settling down nicely using Steveo's Trimalyzer, so a happy camper.
Maybe when i get these up to par.
Is that the fixed fuel pressure one?
I presume i could extrapolate the data from the other Fuel pressure data?
Would that work by disconnecting the vac line to the fuel regulator?
What's your opinion on the Aeromotive one as I was looking at them this last week esp. with a fuel gauge.
How good is the stock unit (23 years old now)?
What sort of power would the stock fuel pump be rated for?
I think I remember reading Steveo damping the map sensor response down to smooth the pulses to the Fuel regulator, Any thoughts on that?
That was in the recent attachment on the LT1 diss zip.
I can't remember who posted it.
I just picked bits of the LT4 tables out that I liked compared to the stock Z28 vs my recent tunes.
Thanks

'95 Z28 M6 -Just the odd mod.
'80 350 A3 C3 Corvette - recent addition.
I am glad your getting closer to the perfect tune.
I only idle the car twice with the regulator so don`t have any usable data how good it is.
I put aeromotive 13107 since I have it from a long time. It is marked as 07/2011 unit, so shouldn`t give any real hints of the unit produced today.
Stock one looked pretty good and as long it keeps constant 3 bar pressure I wouldn`t bother replacing it.
I have plans to bump the pressure to 4 bars and installed it since the rail was off anyway.
I read somewhere that stock pump is good for 450hp, but I am not sure it will handle increased 4 bar pressure.
Patch will work with vacuum disconnected and constant fuel rail pressure.
You will need to have a good injector data though.
I checked a company called Injector Dynamics. They seem to provide good data, but are really expensive.
If you know how much hp you are making you can calculated the size of injectors needed. Bigger doesnt always mean better.
