All,
With my turbo setup I don't have a MAF sensor. I'm working to turn my 02 sensors back on and get running closed loop again but one thing that's always been annoying is the first startup after...
I can give it a shot
What I don't understand is why my 02 sensor output between the two sensors is nearly line over line identical but the LTFT's between banks are wildly different as mentioned above. Thoughts?
It is possible but it wouldn't package well and force me to un-do a fair amount of work. I understand it's certainly more ideal to be bank-bank but I guess I still don't understand why it would be...
They are a long ways from open air, probably 6 feet, the truck has a full exhaust out the rear. The sensors are actually very close in the pipe to where they would be in the factory location. They...
I will do that. I have a single exhaust now with the turbocharger so both narrowband 02 sensors are in the same pipe, a couple inches from each other, clocked slightly different. I could just run one...
Hi All,
I'm at the point in my fuel map now that I'd like to turn the 02 sensors back on and make the final, smaller adjustments through the LTFT. I'm having some issues when turning these back...
Seems to be much more dialed in now. Thanks for the tips!! I just adjusted the timing parameters per the advice.

Yeah super chunk, bad transitions, agreed.
I was thinking of going with SEP's "pro series" injectors as they will grant you a credit towards them if you turn in your previous injectors. Their pro...
Agreed with you guys the lambda is out of whack there. I have had a hell of a time dialing in the VVE with this rig, seems if I make an idle change it'll change me everywhere. I'm aware of the zone,...
Thanks for the reply, that makes sense to me. How big of a change would you recommend? If I'm desiring 25 degrees now, would 22 be a good step? Or should I go more aggressive than that?
Hello, I've got a 2005 Chevy Colorado with an Ly6 and 4l80e swapped into it. Running SEP1000cc injectors, 7875 turbocharger, summit stage 3 turbo cam and controlling it with a stock e67 ecu. I've had...
Sorry total brain fart on my end. I work as an powertrain engineer for a large powersports manufacturer and all the data I look at is in Lambda so that's why this stuff had me confused a bit. So...
Thanks for the reply. I do tune in lambda and target lambda 1 for idle and cruise. I have been struggling to dial in my fueling with a hot engine/ambient temperature. My lambdas tend to lean out a...
Hi everyone,
I've got a 2005 Chevy Colorado with an LY6, 7875, SEP 1000's and a 4L85e. I'm using an e67 ECU. I have the continental flex fuel sensor on a split return line. The sensor is pinned...
Agreed. I'll take a look and report back.
Were they able to remedy that issue with any type of knock sensor sensitivity settings? I will go through the truck and take a look by I'm worried I won't find anything.
Can you expand on that a bit for me? Can something like exhaust rubbing on the body cause it or does it need to be something external rubbing on the block? I can check to make sure the knock sensors...
Vehicle is a 2005 Chevy Colorado, LY6, Stage 3 Summit Turbo Cam, 7875 Turbo, Currently running speed density while tuning VVE
I'm getting a ton of knock retard on what I consider to already be...
Good note on the injector tip offset.
The VVE table. You say it needs some help especially under boost and with the zone boundaries. Can you explain a little further for me before I make some...
Good advice and thank you. I was unaware of the rich after flash, that does make a lot of sense, I guess I'll be waiting at least 20 minutes after my flash to start collecting data.
As for...
All,
I've been dialing in the fueling on my new setup (2005 colorado, ly6, 7875 turbo, dual 340 pumps, boost referenced system) via VVE and speed density. The map has been getting better and...
Digging up some old emails here. Let me know if any of this is helpful
I cannot use a e38, I have to switch to a e67, the e38, doesn't use gm class 2 data, that the Colorado runs on. Factory...
I found this calibration on the forum that's from a 2011 Colorado 5.3
Going back into emails the original OS was meshed to have a 2009 Colorado 5.3 Engine side with an Express Van 4l80e TCM side....
