What are you guys doing about heat soak problems after the truck sits the iat gets to 160 and my fuel trims are extremely lean until it cools back down which can take 10 mins

Did you ever figure out this problem?

No is a 2006 silverado and it's lived over a year on 15psi on a 2 bar map I've been thinking about doing a holley integration harness just haven't went that way yet

Thanks I look into that when I get home this is a 2006 silverado with a 4.8

How would you advise me to fix that problem bc the 2 bar will run up to between 15 to 16 psi and we are talking about 4 pounds more it will ride the bottom row its almost as good to do that then...

It's a stock block 4.8 I have a alkycontrol kit dual m15 nozzles the truck runs on a p59 ecm 2 bar ios which that's all it has no 3 bar capable. Flex fuel is not a option bc we don't have it around...

So I was wondering best way to do this I'm gonna be running 20 psi but I'm on 93 octane I wanna tune on the 93 octane and then when I get done cleaning my VE table spray the meth and pull the fuel...

Widebands don't tune in afr they use lambda when you see 14.65 it's the same as 9.87 tune the same way in afr with your wideband as if you were on regular gas. I wouldn't get caught up in afr I'd...

I wouldn't get caught up in all that for my idle and part throttle use your narrow band ltft tune your idle and part throttle and use your wideband for wot. You afr error is gonna be your command vs...

I figured out the rich problem at idle that's why I had the min fuel milligrams set to 0 anything above that it will go rich in idle.

Engine/Torque Management/General/ECT Limit 12850

Etc limit for injectors if you max that table on my truck it will 3k rpm starts cutting out

Have you ever ran into this problem? At idle or coming to a stop my fuel trims are dead on between 3% and it will all of a sudden my afr will drop to 12.1 and my idle will drop low it doesn't do it...

Wasn't questioning your ability to tune I've tuned alot of trucks also it something I never change the reason being every time I do it on my truck it limits throttle don't know why but does it every...

Was gonna let you know man you can't max out the ect limit on these trucks it will limit the throttle I think there is another guy having the problem somewhere else in the forum with rpm limit...

hey buddy try this and let me know if it works!!!!

the log is for a 09 truck

Without a log its hard to tell . Dont mess with anything under idle except your base airflow and your throttle follower and cracker to help with idle drops. Log short term idle trim and see how much...

And the truck has a 6 speed 6l80 transmission with the stock tune there is alot that needs to be done. At 4000 rpm you have not entered power enrichment yet so there is alot that needs to be...

Your fuel trims look good. With the headers I would try to slow down the oscillation they are switching rather quickly and the shift points need to be raised the truck looks like its shifting a...

You can see in my logs the wave in the wideband signal do you think it might be something wrong with my equipment the wideband or prolink cable

It's just set at 8 degrees until I get my fueling right and I'm on 93 octane probably between 12 or 14 degrees is what I'll run but I'll check my plugs again

My gauge doesn't jump around like that in the truck it's pretty stable

What exactly do need to do?

This a preformabuilt black edition transmission ive built everything to shift at 7000 rpm. I don't used knock sensors I've been tuning awhile now I always read my plugs and try to keep everything...
