There are a bunch of settings that accordingly to the title of the setting help reduce the noise from the hp fuel pump.
It is located under Fuel system/Fuel pump.
Does anyone know what these...

I have chased a problem with my swap. and finally I found my problem. The engine was running on the low octane map which made the suburban undrivable.
The temporary fix was to copy the high octane...

Today I successfully tuned MAF. Started about 14% rich after the 4th log i got it withing 3%.
During the drive I heard a strange noise that seemed to come from the exhaust. I don't know what knock...

I noticed the code also but on the scanner it shows as a permanent code, that shouldn't be a problem. I do not see knock or knock retard. Could the sensor be faulty? I read somewhere that they...

I found out the engine was running of the low octane table, I don't know why.
Copied the High octane table in to my low and now it drives fine, finally.

I still need to figure out why it runs on...

In SD it runs a bit better, in that mode I can get up to speed and it shifts to 6th gear.
But even then when I push throttle timing is going negative.

Also, I can only get it in SD open loop by...

This did not change anything.
The tune I got from CPTuning got me a little better results.

I also tried sd tuning which only worked with manually switching open loop to on and ltft to off in vcm...

Yes, i did do the throttle relearn a few times. I read some need to do this every time the update the tune.
After the first time I do not notice any difference anymore after doing so.

Thank you...

Thanks, I will look in to that.




Engine and trans completely stock, only different thing is the cold air intake with aluminium tube.
And of course no cats. Do have the front sensors and...

No one who can help me even a bit?
A new MAF did not solve it.

I am going to try sd only and see if it drives normal in sd mode.
But if it does I still have no clue on what to look for.

On my 2018 l83 swap I have big negative timing issues.
It seems to drive good until it shifts.
After each shift at part throttle it starts commanding as much as -20 degrees of timing and I can...

It is a cold air intake from Spectre designed for the 2018 Silverado.

I will look over the tune ones more to see if i have missed anything.
On the Open/Closed loop thing I...

The past few weeks I have been reading and reading and watching videos over and over again.
I can't figure out what is wrong. The truck starts fine, and revs up fine.
But when I start to drive ,...

I am going to start at the beginning and start tuning the maf. I have an Innovate LM-2 dual wideband reader so I will try to implement this in the scanner to get better results.
Thanks for your...

So I finally got the Fan installed and working properly.

I ran the engine to get up to operating temperature which took a while and than the van came on nice.
Because I disconnect the battery...

Jip, P0113 is there the whole time. I can't delete the permanent codes.
I read somewhere "permanent" codes only disappear after the problem is solved and the computer was able to recover the...

I have the new PWM fan from a 2016 Camaro in.
I hooked up the wires and tried to control it via the VCM scanner.
That seems to work partially, because the fan wont start at 10% it does on 20%.
But...

I haven't noticed any special settings in the tune.
It did run ok for a few moments. without the engine running.
When I started driving the engine was no where near the operating temperature. So...

So i got a new unit installed and it worked like ok while testing in VCM scanner. Fan has to be set to PWM EV(not PWM Electric)
I changed some things in the tune and reset the LTFT and some more...

Thank you.
I will do some mor reading before I do some more testing.
I also have an issue with the fuel pump I need to figure out.
And i need to come up with a solution for mij backup lights.

A...

Thanks for explaining. I will try a few runs with MAF disconnected. The log does not show speed density. So it did indeed not reach that mode. I'll do some more testing.

At least it is drivable now. So now I or probably someone else can start to tune.

But I am still puzzled with that disconnect and reconnect thing.
Could this mean that the MAF is faulty. Maybe I...

I have an aftermarket open air intake installed from Spectre. Its an aluminium tube so there is a difference. I don't know the diameter of the original tube. I would think the engine should run...

Another day, another try.
After reading that a faulty MAF could do strange things I thought I'd try it with the MAF disconnected.

So I started the engine let it idle a few seconds and...

Yes I read some about the sensors to log. VCM also has built in a preset for the 2018 Silverado.
That is what I used on the latest log, together with some extra sensors.
Not all the selected...
