Is my 86 healthy??
 

I looked at my diagnostics with the OFT v2 tablet and wanted to know if everything’s running fine. I had it parked and idling while I ran the diagnosis. But as far as under the hood goes I’ve only added JDL UEL headers, a GrimmSpeed CAI and the Remark x FT Speed Quad Catback exhaust. I’ve had the tune on for some time. And I do my regular oil changes every 3-5k miles.

Better do a Compression Test and Blackstone Lab oil analysis.

What do you see that leads you to make that recommendation?

:iono:

You don't see it? I see it.

From what I can see, none of those things on the OFT indicate there's a problem.

I think the better question, is why are you asking if it's healthy? Is it characteristically doing something wrong? CEL? Running rough? Weird sounds?

If not, a compression test and oil analysis will tell you more.

OP, Teseo's just yanking your chain. ;)

While driving, glance at your long-term fuel trim and knock correction for the most important indicators. LTFT should be within +/- 5% -ish. Shouldn't have any knock correction.

Looks golden at idle.

OK, soooooooo, ya wanna share what you "see"?

:confused0068:

I see a smoothly idling engine. ;)

Numbers on a screen! duh!!:bonk:

Uhh... Advance multiplier is 0. That seems bad. You normally want that at 1. (Edit, unless the tune has IAM set to 0, but that seems odd for an OFT tune)

OP, take a log and post it to datazap or something. Screenshots don't actually tell anyone much of anything.

Also an oil analysis will tell you how the hardware inside the engine is doing.

Edit:. Wow, how'd you screenshot stft at 0? That's normally all over the place.

Depending on injection mode it could go to 0 on stft I believe. That's why you usually log injection mode too.

IAM at 0 is weird. I almost think there is an issue with the OFT reading correctly. Possibly need to unplug and reconnect the OFT and the cable into the OBD2 and check again. If it was actually at 0 on IAM it would feel really really sluggish.

Hey, you're right!

I even knew about that at one point... :bonk:

I see that now! Thanks for linking threads. :cheers:
