Yea, those guys were firing phasers at each other. It's been a long week, I needed the laugh. The other guy helped write the fueling for GM? I need to go back and read that again.
You can have all the Pepsi you want. Don't resist; it's ok, the guys in the white smocks are here to help..
Yea, if you have the existing code and credits to license them. I remember two credits for each computer. You can find stock code here in the repository if you don't have yours. It's in your user...
Thanks for the lead. Work got crazy, I let the shop take care of it. I have a 415ci short block I'm going to put in next summer.
The plan is to use a close to low duration cam and install a...
Thanks that's good information.
Ok here's a couple more questions I've been meaning to ask. Are the 8L90's a more reliable trans than a 6L80? Do they cost less to rebuild? The reason I ask is I...
Hey Y'all,
Can I program a 6L80 TECM with my old config if I replace my trans with a unit from Jegs or whatnot? Or does the GDS do some kind of proprietary initlization(sp)process for it to be...
I've been doing a fair amount of logging on my L86, diagnosing issues after an engine install..
Will normal driving logs with shaft speeds do you any good? I just happened to be looking at my...
Hahah.. Now I'm wondering if I did the same thing but I vividly remember plugging it back in. I fought with that connector for a good long time after mis-routing the harness. I didn't reinstall my...
Thats cool, I want to pick your brain about that more.
Can I plug in ECU from another engine to my existing harness and pull the config and vin without messing anything up?
I'm having this exact same problem. P06DA and P06DD. I was fighting with that connector for a good long time too so it's got to be electrical. I got the engine in last week. I turned off the PID's...
Yea, that's good to hear. I recently got my 07 F350 dialed after 2 years of head scratching. I'm trying to get ahead of it by digging into others logs, building up histograms, graphs looking for...
Yea Interesting I was looking at the tune you posted.. Thats good to hear you're sorting things out.
Ok thanks for the info. I'm working on a stroked 6.2 and will be adding a turbo at some point once it's in the truck..
Disregard that.. I'm still working through what's normal and what isn't. It looks like the eq ratio error will go to 100% error under deceleration. I added the channels I use.
Yea, I have a...
What was it?
Hey,
If you don't mind, can you use these logging channels and do a longer log of like 15-20 min when the engine is good and warm? You last log the engine was just getting up to temp and there's...
Hey, I'm just poking around in your logs trying to build out a VVE histogram and want to point out that you're EQ ratio error will go to 100% @ like 1300 RPM.. Prior to this event the STFT averages...
I don't understand which way the #'s change things, hoping you can explain because I'm not grasping the concept. Previously you had posted something about the map transfer function with the first pic...
This is helping me work through this too. Can you go back to the stock file and get a good log like you posted? You changed so much it probably makes sense to go back. But this is worth a try.
...
I'm not really qualified to speak to this but I don't think it's the trans.. Look at the TQ management kicking in.. It's not showing detonation.. It looks like driver demand is kicking in and it's...
Hey everyone,
My 15 Yukon engine tore up due to typical problems related to DOD parts.. So I need to build a new engine, which is in the works.
I decided to go with a 4" crank and I have...
OK. Wow.. thanks.. I'm going to need time to digest this.. Couple questions that come to mind:
Can you share some more of your math equations to help with my logging? What do I log to see the...
You know what was hunting me? This idle problem followed me from this tuning I paid. I think I gave them enough time to figure it out. It would idle fine cold but once it warms up it'll start to idle...
This has been a 3yr journey. Back in Dec 2020 I bought this truck DOA from a Copart auction. The last diesel I worked on was more than 20yrs ago in the Marines. So all this is totally new, the engine...
