Got a 94 1500 with gen3 4.8 swap, is it tuned?

[vziel]

i recently purchased a 1994 Chevrolet 1500 single cab short bed with a gen 3 4.8 swap already done.
it is setup with manual trans (nv3500) and i see that it has no 02 sensors at all. it runs and drives pretty well but i have no idea what has been done for the tune.

I have hp tuners and credits i need to tune. I linked my tune (i think) so if anyone can give me an idea what has been done with it i would appreciate any input.

well i compared your tune to another tune and someone has adjusted things within your tune.

Now what does that mean?

Until you start datalogging it to see how it runs/performs, it really means nothing much more than just a good conversation.

Do you know what to do to start datalogging?

It is a calibration from a 99 Silverado 4.8L with an automatic transmission (4L60) and you said your swap is using a manual so that alone makes it incorrect.

with an automatic transmission (4L60).

nice catch

i did a data log or 2 recently but i don't have all my stuff set up correctly yet. i did try and set it to manual but it would just fall on its face at 5 mph so i reverted it to how it came again.

Is this a stock engine? The VE doesnt look great. Fuel trims and closed loop are set to come on, so trims should be working unless you physically dont have any sensors. TBH, i owuld compare a stock file with the same OS and i would apply pretty much all changes back to stock. Your timing tables and idle timing tables arent so great. Overspeed and underspeed has been fudged in an attempt to make it chop im guessing?

You didnt give us a list of mods so ill assume its all stock. We need a part number from the injectors that are installed. Id starat from a new file. I bet it'd run on its own if all the stock data was placed back in the tune.
