Was actually something really silly - DOD was still enabled in the tune. I made the assumption of thinking that because I had a stage 2 cam, it was a given that I would have deleted dod

I just completed the install of a TSP stage 2 cam (with all the usual afm/dod/vvt delete, dual valvesprings...etc). Started it for the first time and it is running SUPER lean. narrowbands wont even...

Ive just completed the install of a TSP stage 2 cam (arm/dod delete) and long tube headers for a friend on his 2010 Camaro Auto.

Is there some basic settings I can use to get him up and running...

Thanks for all the pointers, I'll have a go at playing with the torque tables.

I'm not exactly sure what the car is putting down as I haven't had it dyno'd yet, but I'd estimate somewhere in the...

@cadillactech - I looked at someone elses stock file from a M7 C7 Z51 and my driver demand rows seem to be exactly the same. Were you maybe thinking of the A8 tables as I downloaded a tune from that...

OK I'll see if I can find the stock file for my car and copy over the tables from there. Can you think of any reason why someone might have changed them? I've been through several tuners so its hard...

Here's the tune file I was running during that log. The tuner switched to SD tuning at my requests as I was getting fed up and wanted to try something different.

Car is a 2014 M7 C7 Stingray,...

I'm hoping someone will be able to assist me and my tuner in locating the source of the issue I have been experiencing with my tune...

If I gently pull away in 1st or 2nd, at about 1,500RPM the...

Or any remote tuner recommendations?

Thanks for the info. Any suggestion on what I should reduce the values to? I'm new to all this.

Hi All

I'm having an issue with my tune where I seem to have a 'flat spot' at around 1000-1100rpm.
It is most noticeable in 1st and 2nd gear when pulling away gently with a little bit of...

Yeah you're right. I just started the car slowly revd it to 3k rpm. It started stumbling and misfiring AFR's in the 12's.

Hoping my tuner will get in touch to look over my log.

Great, thanks for the confirm. I know the general consensus is to go secondary port injection when you start hitting big numbers, but sadly (for a few reasons) that's just not an option for me. For...

I've just upgraded from the OEM LT4 injectors to the XDI LT4 +30% injectors on my car that has an LT4 HPFP with a +32% fuel lobe cam and a DSX low side secondary pump.

The calibration sheet that...

veee8, WHAT DID YOU DO TO MY CAR MAN!!! Before my car was "damn thats fast", and now its "arrrgggghhh holy *&!@ thats fast!!!!!!!"

That second tune you sent me, wow! Not only have you totally...

Thanks so much veee8. I can see you've made quite a lot of changes, so I really appreciate the time you've spent on this. I will try this one tomorrow and keep my fingers crossed :)

veee8 - I just gave it a try and it is MUCH better. Instead of hitting the limiter between slow changes it now seems to hold the the RPM. So If i change at 5k, it will sit there for a few seconds...

Thanks veee8, I'm going to load that up and give it a test asap. It looks like you made quite a few changes, so thanks so much for taking the time.

I'm in the UK and the engine is fully built.

The first tuner I worked with wasn't able to get rid of a 'flat spot' at about 3,500 where I would press down on the accelerator, nothing would...

To cut a long story short, my car just doesn't seem to like being tuned in the conventional way. I've had 3 tuners, all who have criticised each-others work, and all who have failed to provide me...

No idea about the MAF scaling. I'm using the stock MAF with an IAT and BARO breakout harness. I've marked the location of the MAF (red), IAT (green), BARO (blue) in the image of my engine attached.

My tuner made a point of requesting my stock calibration when he started working on my car, so I'm pretty sure he worked from that. I will see if I can find that file again though and do a...

Here's the last tune I received from the tuner and the log file associated with that tune. I'm not sure if the log caught the issue I've described, but I've been doing my best to avoid the car...

With no reply from my tuner (anything could have happened in the past year I suppose), I may now be looking for someone to complete this tune for me. Any takers?

Thanks for the reply. I'll pass this on to my tuner and see if they can use the info you've provided to get to the bottom of it.
