It you decide to tune on a dyno or have someone tune it for you on a dyno, don't waste time or money getting the airflow correct on the dyno. Do maf and ve on the street. Then only do timing on the dyno. If you don't give a **** about fuel mileage, then only worry about the timing at points when your at wide open throttle.
It has been a while since I messed with hpt, but last time I checked, we still cannot change timing on the fly like the v8 engines can. So dyno tuning timing would take forever if you are going for fuel economy at every point in the map.
Sorry if the post sucks. On my phone. Thread has been interesting and sad at the same time

I agree. We pay just as much for credits and software. Why did we get less support? I say that in past tense, because I would bet money that hpt has forgotten about this platform since the ecu is no longer used. I am talking about lsj anyways. Can't remember what the lnf used
Edit: I know why we didn't get support. Its a numbers game. They made less ss cobalts than v8s, but it's still frustrating

good points! when my tuner and i tune, we go and literally cruise for an hour or so. thats when we sit and dial in the fuel trims for daily driving and drive ability. we will do 1-2 pulls on the highway where there is nobody around and get some good data to check for knock and to see if we need to pull or want to add timing. all of my tuning has been on the street and this car has not given me a problem in the 7 years ive owned it.

Support was a wrong choice of word on my part

yeah, and I'm a bit skeptical that a dyno tune is worth it at all on a high boost turbo application. Any timing you can throw at it should be an increase in power. It seems like the lower compression naturally aspirated engines are where you find sweet spots in timing advance.
yeah they support it, I just mean that they'll never continue to unlock new tables on the ecus that we don't have access to. Or get us the scanning tools like the v8s have that allow for on the fly timing and vvt changes like ecaulk mentioned.

you run the timing up until you hit knock retard and then kick it back a couple degrees. Knock retard happens long before you lose power on these cars as well as most forced induction engines. If it didn't, no one would be interested in e85, methanol or other octane adders. I am assuming that only people with sense are trying to tune their cars. I'm not saying to set your entire wot portion of the map at 35 degrees and run it.

[QUOTE=ECaulk;7686952]You should be fine on e47 to push it
maybe ill add some more to it midrange and go up to 24-25*. up the boost or keep it at 22psi? whats the highest youve gotten out of 93?

thats right you guys have 91 lol
