verify that that is the timing you are actually getting with your EMU log. a bad ECU can make timing report wrong also, but the EMU actually calculates it from the coil, cam, and crank raw signals.

[BlackStealth]

If he gets severe knock, timing will be pulled a lot, so 12 degrees doesn't seem unusual at all then. Perhaps we need to know what is his timing just before knock starts.

Pulling a degree or two beforehand on emanage can prevent knock entirely instead of relying on the ECU to aggressively pull large amounts of timing.

Im at work and im not 100% positive but im pretty sure i dropped from 32 degrees to 12......

[SirLaughaloTT]

well Im home now and got my logger here is some info for u thanks for the help....

spike 18 psi drop to 17 2nd gear pull

peak: Rpm-6000 INJD-96.0% KNCK 10 02-R 97V 02-F 99V TIMA-12 degrees

start of knock- RPM 3406 INJD 19.5% KNCK 6 02-R 93V 02-F 95V TIMA-25 degrees

Before Knock-RPM 2593 INJD 7.0% KNCK 0 02-R 82V 02-F 62V TIMA- 35 degrees

Ok here is an update not a good one on my part though

I don't know what happend maybe the cold weather but i hit 19 psi
and over 100% injector duty cycle witch i know is not a good thing..

19 psi

RPM 6875 INJD- 105% KNCK-0 02-R 97V 02-F 99V TIMA 23 Degrees
TPS 98.0%

looks like you need to take some timing out at lower boost. EMU Logs would be nice also.

im not sure how to upload my e-manage logs... other wise i would

Alright, I think I am finally to the point of asking for help. lol. I currently have three issues that I am facing. A little bit about my setup:

I currently have the e-Manage Ultimate in Stage 2 setup for speed density so I am running the Airflow output map. I am using v2.16. For right now, I am running stock 360cc injectors with Gray Hazes’ “stock” airflow output map. I am just using these for the initial break in process and will eventually go to 680cc. I am also using the GM IAT and resistors to keep the barometer static. I also have an Innovate LCI WB hooked up.

And if it helps, here are my mods:
EVO3 Turbo Kit
FMIC
"No-MAF" Intake Pipes
Stock 360cc injectors
Denso 310lph fuel pump hard-wired
SX Fuel Pressure Regulator @ 43 PSI base pressure
Rebuilt Throttle Body w/ new o-ring – FIAV blocked off


The first problem is, I am getting a really bad idle surge and I can’t tell if it’s from the Emanage, tuning or if it’s from another issue all together. I just did a throttle body rebuild w/ FIAV blockage in hopes it would help and it didn’t. I am going to be pressure testing soon to rule that out as well. I was hoping to go back to the MAS setup as I had before my engine rebuild to rule out the emanage. But the turbo intake pipes I have not will fit with the MAS. Should I try to rig something up to go back to the MAS?

My second problem is just adjusting the idle tune. I can definitely tell this map is very rich just for stock injectors. I have the Innovate LC1 hooked up and during startup, its pegs out to about 17-18 AFR. I know you are not supposed to tune with a cold engine, so I let it warm up and it still runs very rich. I guess my first question is, am I supposed to unplug the NB 02s to keep them from interfering with the ECU while I tune? Secondly, when I change an entry in the map, it appears to change the AFR at first, but then it seems like the ECU re-adjusts and either just goes way rich or way lean. I know that it’s working correctly as if I do a MAP trace, and find the correct field; I can shut the engine down by typing in an extremely large number. (Did it on accident once..Oops)

And my third problem is the same as a problem listed earlier with throttle tip in. It seems like whenever I go WOT, there is a lag. I have read that this requires use of the “Accel I/J Adj map”. My only problem is I am on stage 2 and not 2.5. Is there any other way to fight the lag or do I need to go to stage 2.5? Also, I noticed Trevor is only at stage 2 and didn’t see anything about him having this problem.

Sorry for the book, but any help would be appreciated. Thanks!

Gray Haze's stock 360cc map is not perfect, but it's a pretty good start. Like you, I had idle surge and had to reduce fuel on one cell to fix it, and it was all good after that.

Tuning speed density is a lot more work, and requires a bit more skill than tuning a MAF. Without throttle tip in correction, you'll run lean temporarily and you must resist the urge to correct it on your map otherwise you'll mess up your map. To go to stage 2.5, you only need to hook up 7 wires and move Jumpers 1,2,3,4,5,6,18 and this will give you acceleration map to combat lean throttle tip in.

Thanks for the quick response.

Just to make sure I reading this correctly from here and in the manual, lowering the Hz should lean out the AFR and increasing the Hz should richen it?

I have also noticed by looking at my pocket logger, that the Hz doesn't match up with what I have in map. I am assumming that since I am at an RPM between what is set in my scale, it's just trying to compensate for that.

As for going with stage 2.5, do you think it would be better to just go stage 3 at this point. I know you said you were having problems with it, but is tuning speed density easier this way? I am just trying to figure out instead of soldering 7 more connections, if I should just get the boomslang harness.

Sorry for all of the newbie questions.
