For anyone that followed this 3 bad injectors is exactly what caused this issue.. and it DID hydrolock. The mechanics also found leaking valve cover gaskets as well. After draining the oil and...

I agree. This setup was put together elsewhere completely and I was just consulted to help with the idle/shifting/starting behavior. Hoping to hear more from the guys soon. But hey man, thanks for...

Starter tries but won't turn. Oil smells like gas. My friends have taken the car to their shop at the moment so I'm awaiting further info.

The intake is the Holley Sniper sheet metal (loud AF)...

So long story short I spent a couple of days smoothing out the idle and shifting on this setup. This was a final drive around the block and the car ran fantastic the entire time. If you zoom to time...

You're seeing 4 degrees of knock retard above 6600 rpm. Seems like you're gonna be capped at about 16-17 degrees. What fuel is the car on??

Any chance it could have something to do with the Aircharge (Load at WOT) table under the speed density tab?? I noticed in the log about the time it hits FMEM desired load is around .84 at 2800 rpm...

Any resolution yet on your throttle closure. I'm having the exact same issue on a 2013 ST I'm working on. No torque sources show at all and I'm getting the exact same throttle closure around 4200 rpm...

Disregard

I'm looking for some help in reviewing this datalog and finding the issue. I'm helping a friend try to sort out some issues he's having with his box Chevy with a 5.3 from a 2016 Suburban. In a...

I haven't done an IMRC delete personally yet but right away I noticed under the Variable Cam tab you still have all the IMRC mapped points enabled and commanding them in the distance tables. That in...

Cadillactech do you mind elaborating a bit on some of the filters you recommend for VVE tuning. I've seen you mention that on more than one occasion. I'm relatively new to tuning, haven't touched a...

For what it's worth the intake manifold volume has not been changed to the correct spec if it's got a Boss 302 manifold. Should be 11.74 L. Not sure on the flex issue. But that volume isn't helping...

Thank you for the input!

Hey guys,

Honestly I'm still new to the tuning game but have done a few vehicles at this point, mainly a few Coyote cars including my own. However, I'm going to be attempting to help a friend get...

Second the above. Idle airlfow final minimum needs to come up to close to what you're seeing in the logs. VVE and MAF curve both need work, done so independently. What's up with the timing tables?...

If the truck is stock or mild bolt ons I just can't imagine recalibrating the SD would be of any benefit, especially with trims that close. The fueling is close already and unless you've changed...

Thanks for the input! Your suggestion is what I was getting ready to try as I've noticed small discrepancies from log to log. The spreadsheet idea is just what I needed. Sounds like we think alike......

I should have added originally that I calibrated the MAF using the method described and got the fuel trims pretty damn close at <2% across the board except idle. My idle trims are roughly 10-12%...

I honestly hate even asking this question considering how many times it has been asked. Is there anyone willing to share the CORRECT/CLEAR procedure for calibrating my 2012 GT for my JLT series 2...

Not sure by any means but it hitting Cylinder Pressure limit may very well be contributing to that issue. I noticed when tuning my S197 any time I hit any limiter (torque trunc, cyl pressure) the car...

It appears that timing pull is when the trans is changing gears. I noticed the same thing when I was tuning a friend's truck. It is a form of protection that reduces spark temporarily to soften the...

Its got some key tables zeroed out. All of the distance tables under the Variable camshaft tab are zeroed. MAF temp compensation is zeroed. Looks like all the torque tables have been scaled and tuned...

Im open ears on this one. I've been working on my ghost cam tune for 2 days. Ive got the idle sounding good and stable, normal drivability is perfectly fine. But when I floor it the car hesitates...

Same to you. Sounds like a fun one.. lol. Just curious if you're seeing anything strange on the spark or torque source while it's happening? If you think about it I'd like to know what the issue ends...

If you are referring to the Torque Truncation its in the Trans tab>torque management... I maxed out the values for all the gears. Mine had values of around 370-400 ft-lbs in the factory table.
