Ok Ill start there
This is the file thats in the car currently. I have only tried to use the o2 proportional and take timing out of it. Sorry I should have specified
Battling a light throttle surge on a friends 09 vette all stock minus kooks long tubes and 225/236-114 cam. Car drives great minus a small surge at light throttle. I have been reading on other...
I will check for a vacuum leak as well or see if the bov is leaking
Ok. I will give this stuff a shot. I appreciate your reply. Do you have any tricks for the rear o2s?
It has reference to the regulator and it doesn?t have a maf. Any of the other stuff I have ever tuned that is speed density has always had the maf codes set to no mil light so your not staring at a...
Not running on the narrow band sensors at all. Tuning it in open loop with the wideband. Aem 30-300 wideband
Had a local guy drop off a truck for me to tune for him. He just bought this unfinished truck that supposedly just needs a tune. Well the truck starts and runs great in park but once you drop it in...
I had read a post where James Short from Shortuning said that he leaves the 4l60e option in the drop down and shuts off all of the transmission codes and tm instead of changing the drop down. Stall...
Fighting a surge issue and stalling when the truck is put into gear or if light throttle is given then taken away like driving in a parking lot. Engine is an 04 5.3 with a small cam using the stock...
Tires are just a touch bigger than stock. Height wise. Im not sure what size they are this is on a friend of mines truck. The speedometer was off about 5mph with the new wheels and tires so he wanted...
Anyone run into an issue when changing tire size and gear ratio on a 2005 silverado 1500 2wd and it setting the traction active light and pulling a bunch of power out when you get up to speed say 60...
So I am new to the gen 5 tuning stuff and a friend of mine brought me a 2017 silverado 5.3 with a btr stage 2 cam to try to get a tune worked out on. I am struggling with this thing. At 2:16 into...
I set it to 80 counts and that fixed the park to gear issue so thank you very much for that. Do you have any thoughts on throttle blip in say a parking lot and then it wants to die instantly after...
Is there a reason why adjusting the iac counts is better than just giving it more throttle blade with the screw?

It still wants to under run and die once in a while. I even bumped the counts up to 60 in that area where you changed it to 40. But it still wants to drop down to around 500 rpm. Sometimes...
I will give it a try first thing in the morning. Thank you
So I got this 8.1 dbc stuff figured out by using a bone stock 6.0 file and transferring over the inj date and ve table from the 8.1. It now starts runs drives great my only issue at his point is my...
I do have the etc shut off in the system tab. Yes I am using hp tuners to tune it.
Using a p01 ecm. The 6.0 os is a 12208322
The 8.1 os is a 1272013
So Ive recently swapped an 8.1 into my 86 c30. It originally had a 6.0 4l80 combo. Ive got the truck running good on the 8.1 avalanche file but Im not getting any actual iac counts but I get desired...
I use the same 3 bar afr error histogram on other stuff and it seems to be fine on all of them. I can try to remake the graph and see what it does differently.
Setup is a 4.8, btr stage 2 truck cam, boost reference regulator base at 43psi, genuine bosch 1000cc injectors from sep, s475/83, 4l80e. The ve table is jacked I know but thats what it shows it wants...
Cant get this truck Im working on to maintain a solid idle afr. Get the afr nailed using rtt then load the new tune and fire it up. Then it idles super lean like 16.5 then I go drive it and come...
So I have adjusted all of the limiters so that it goes full fuel higher up in the rpm range and smoothed inbetween but it still gets to a point to where it fuels really hard. It seems like I can not...
