That helped. Thanks. Still have a little knock but you can't feel it now.

Would you be able to feel that small amount of timing being pulled out? It almost feels like a misfire. Or is it more likely I have a misfire that's causing it to pull the timing back?

More questions. My VE error is within +/-1% now thanks for that. So now I'm adjusting my spark tables high and low. It was pulling timing out in the higher airmass and rpms so I dropped the lower...

Thanks. It's running much better. Embarrassed at the amount of time I spent on it to not really get anywhere. But I appreciate the help a lot.

Here is the log from today.

This one.

No I'm sorry for some reason I thought that was the attachment I posted.
I will put that in tomorrow and re log if youre still willing to help then.

I just went for a drive and logged this.

I planned to run both MAF and SD. And I know it's not finished. I dont have a WB on it right now I've just been working on the cruising area. And I know that area is still a little rough I was just...

Ok I've applied the SD 1 Bar OS. I got the VE table in the cruising area done. Havent really touched on the other spots yet. Swapped back to MAF and now I'm having trouble getting it right. I'm...

Ok thanks for the help. This truck was originally tuned from another shop MAF only. The truck ran terrible so I'm learning and trying to straighten it out. Just trying to make sure I don't grenade it.

So I'm still learning a lot of this. Please don't mistake this question as me doubting because I'm not. But does the original OS blend MAF/VE?

The OS options are SD Enhanced, SD 2 Bar, and 1 Bar MAF Enhanced. Just do the SD Enhanced?

Thanks for that. That helped. I know the transitions are still a little rough. But it is working now. I ran out of time but this is where I'm at. I've got some issues. This thing will not idle in...

I'm working on a 99 5.3 with a chinese 2 stage cam. It was extremely rich and I got the MAF calibration done. Runs ok MAF only just start up can be a little rough. My question is in speed density I...

I've posted before and I'll state again, I'm not a tuner. I am a tech. With that said I have a customer that has done a 6.0 swap in an S-10. He's 80 years old and wanted a project. The local tuner...

Is there actual tuning required? He has HPT but isn't good at using technology. If it's as simple as a disable function I could talk him through it but I don't do any tuning? Not asking for anyones...

I have a friend in another shop that took this truck in needing timing chains. It had no power with high knock counts so he replaced all timing components with OE parts and locked the phasers out. He...

Thanks for your advice. I will let the guy know and he can make the call on what he's going to do next.

This kid ordered the cam not knowing what he was ordering. He's a gearhead and likes turning wrenches so he put the cam in himself. He paid $500 for this tune and when he left the truck would barely...

I am not a tuner, I am a technician. I use HPT for things like disabling features but that is about it. We have a customer who put a stage 2 Low Lift cam in their truck and had it tuned. The truck...
