I am hoping to see what is available tuning wise and what sort of access we have to
the emissions equipment for testing and scientific information purposes. Is it similar
to what we can access for...

Locked?

Shoot me a copy of your tune maybe i see something of interest. Got mine running like a dream .

Could you elaborate a bit more on this. Its a custom tune but the tuner used Edelbrocks injector data and TB data for the ford racing 90mm .

Just for reference mine is a manual car with the EB 2650 and 90mm TB. When i do a blip of the throttle for a downshift the engine kind just coughs for a split second other times its fine. Just...

Have you made any progress on this. I just replaced my injectors with FIC 's and am tuning the MAF but i have this little tip in type cough sounds similar to what your going through.

Hey

So i have VCM suite installed on 2 of my computers working fine for a lot of years. today i installed it on my kids computer (30yr old) and when i open a file and try and look at a timing...

i have some tunes from blown f150's if that will help. Its how i learned the little i do know. I gathered every tune i could find.

Thanks for the update always nice to have a thread finalized. Funny the o ring was gone but that totally makes sense.

Yes you have a map sensor, the ford trucks are speed density. The tuning school has a book but does not cover SD and online interactive training as well. Im not sure how much info exist for speed...

A boosted car does not need a map sensor and you can run a lot of boost through a MAF these days . Fords strategy is all torque based , and everything else is inferred like you said with quadratic...

Is it a lightened flywheel. A guy i stumbled across on youtube is going through the exact same issue since he changed his clutch in a Boss 302 and it has been ongoing for 4 months at least. There is...

Aluminum flywheel by chance.

As said above you will get more help from a log than the tune. Then we can see how much timing is coming in and from where and what MP your pulling from . I found out from some one here you can...

Not getting help makes you work that much harder, better that no one had seen this before as it made me put my mind to it. That is interesting it chooses the lower number good to know. I try to solve...

For anyone interested, i poured over logs for hours looking for a discrepancy , and systematically went through the editor comparing my stock Edelbrock tune to the one i got from my tuner. I could...

Ever since i have had my car tuned i have noticed that when i go WOT my fuel source shows it starting out as cold eng/startup . The tune that came with the blower from...

Just a shot in the dark, but maybe the bypass valve is giving issues you need to test it with something like a mityvac that will apply vaccum and pressure . Also with scanner connected to the car you...

Its all about interpretation and i can tell you that reply from eric is vague at best but i got what he was trying to say and its how i was using it from the beginning until someone psssst in my ear...

I will put this here just so the any confusion on this subject will be final. Per Eric at HPTuners

Hi Richard,
It follows the firing...

When i started hotrodding cars 40yrs ago i had a more is better attitude luckily i didnt have boost. I much more conservative in my approach and make small changes and do lots of logs. Going for...

Sounds like a very solid process and i am open minded enough to look at all opinions. My self i have since made some minor mods in my borderline map points and things are working decent. Nice thing...

Merely an example from a process i am doing on my own car. If its lower than whats at .95 thats where it will go. Im PD so boost is instant, turbo cars are entirely different i suspect.

The dyno operator should know what he is doing. If you car is tuned different in different modes you will have to decide which mode you want tested in. Honestly a dyno is there to prove before and...
