Ok I was like... that dont do that tho haha
How do they keep breaking features that worked fine for years? Like the TCC lockup button logic reversed on some Gen3 stuff when it was correct for 15 years LOL. Im pretty sure they are doing it on...
How does Injector Density table help being a ITT vs Rail Pressure table on high load low rpm spark knock?
Tried every pid available, seems like itll read in combination with some steady for a while delete a pid and then reads 0, no rhyme or reason just 58 0 57 0 57 57 0:shrug:
Look at Fuel Pressure as...
Thats what I was thinking, why they have the offset numbers all over the place from the factory beats me, Ive zero it out
Hadnt thought to look at that, these runs were 1.012 and 1.000 that...
While were all having fun in here, lets talk injector SOI and alcohol offset. What are you typically doing for this, if it likes say 360 on pump gas what are you finding on 85% ethanol?
Also,...
So, this is fun. 2020 Camaro SS, with both ABS fuse and j case square fuse pulled, in 5th gear must jerk the brakes to make that dip. Doesnt do it in 6th for WHATEVER reason (although reads a few hp...
Alvin you know - I never thought of that because all the older gen ECU turn them off automatically under load, but no climate is off
if you set the disable to 4000 and reanable to 3950 does that...
Can see a subtle dip, but not the chunk out like all the previous
Graph
Well, after finding some things - some burnt looking plug wires, pinned against the headers, LTR5IX plugs that looked crusty and were apparently reused when the motor was pulled out to do the cam...
I think you and I have shared a hatred for TSP valvetrain products for some years now. The Tsunami cam, jeebus what a headache lol
The cam is supposedly something recommended from TSP for no converter. 227/231 is the specs I was TOLD. That's not real big at all on exhaust closing side especially at 116 lsa but again I'm not...
I think I mentioned it, but ive tried SOI up in the 350s-360s. Lost like 20 hp I think?
Look at the dyno graph right above, the dip does not coincide with timing being pulled consistant either....

Run16 and run19 same tune file, richer one actually made more power
Run15 & 16 had same tune file - 15 first pull I made that day and was way lower (100hp) than it was the night before. Changed nothing and ran back to back and it made the best power it had Run16. if...
So with tank on E put 5 gal of E85 in, 67% on flex sensor, injector PW actually did jump up (but not enough, AF was 12.3 on gas and 13.12 on ethanol) usually i dont see that much discrepancy in air...
You know Id tend to go there, but new spring/cam kit from BTR or TSP I think the guy said
Even lowering low side pressure from 72 to 58psi, and hi pressure all the way down from 2900 to 2100psi -...
LT4 pump supposedly, lt4 injectors, cam with 34% lobe on it, with all the LT4 info in it and axis mult by 34% Im still seeing a spike after letting off from commanded 2600psi to @4000psi? This is on...
Dip you can feel and flat up top. No TPS closure, no kPa showing vacuum, timing at 15 degrees and KR isnt spiking right there making a dip
I did find that some injector data was wonky and made sense that the airflow model need bunch of fuel pulled out at first. Still waiting on word from the guy if he puts 87 in the thing lol (or maybe...
So, anyone ever come up with comprehensive list?
Have you seen pulsewidth too narrow be a problem? As long as pressure isnt dropping I wouldnt think it would matter if it gets enough fuel in the cylinder
Car was previously tuned, has BTR stage3 cam 34% fuel lobe, LT4 injectors/pump but is dooky at WOT (410hp 410 ft lbs 11.7:1 air fuel) First headache was figuring out some spacer plate was used (less...
Did the guys having spike problems and not seeing expected results with this table, find that they were starting with wrong table? Or still doing the odd stuff regardless?
