I picked up a Stealth Ram 350 with ported heads and a larger cam and I'm looking for someone with a similar setup as a starting point bin file for tuning. Sorry that this is borderline begging, I just need a starting point since I'm new to the whole burning/tuning aspect and I want to be able to move my car around my garage/work area until I can afford a wideband O2 setup.

 

U "dont" have to have a wideband to work on the tune.

Ideally start out with a $6E or 32B bin for a 350, assuming it is still MAF.

Set all the constants to the correct values like the Injector Constant.

Try making a realisitic 10% out of the lower fuel tables and adding some idle timing.

MAke sure the basics are good and the rest is not to difficult to work out.

Depending on the cam, bump the idle rpm up higher by a 200 rpm when hot and also take the time to set the TPS and IAC as this will help idle funtions as well(set IAC to little or no counts at idle hot)

The wideband will make issues easier to solve because they show up easier, and let u dial in settings for optimum performance(when worked in accordance with timing).

Wideband is a great tool for tuning but it is an aid above all else.

Work slowly and look up terms unfamiliar to you and you will be okay

If you have iron heads, stock 90-92 L98 f-body. If you have aluminum heads, stock automatic 90-91 vette.

 

Ported iron heads from an 87/88 camaro, with Speed Density conversion- not MAF.

 

In that case I would get a hold of the stock SD L98 f-car tune for your baseline. It won't run very well before you tune it, but it's the best publicly available match for your car.

 

Alright I'll do that then, just sort of hoping someone had a similar setup.

 

Someone could, but you'd never know what all they changed. IMHO better to start with a nice virgin BIN, and figure stuff out yourself.

EDIT: I think I have a copy I can send you.
