Hi. How are ya.

The pics below are pretty accurate examples of what my dashhawk logs usually look like. I know it's a stretch, but can any of you wiser tuners glean info from this, or from anything else I could log and provide, that would help me dial my tune in. I've crossed the boundary into "DIY tuning" (HPT Pro), and while I feel pretty competent in my abilities, I am still new at this. :cheers1:

BTW...nothing is wrong with my current tune. I am still very happy with everything Cory set for me, but I am prepping for some new additions, and need to be able to make adjustments myself, on a whim.

I'm not getting the misfires...is it just me or is it missing?

12 total misfires isn't too bad.. Thats a count for all 8 cylinders... I get misfire when coming to a stop with the ac on.. Its right before it switches to the idle spark tables (3mph) versus the coastdown spark tables 3mph+ and in decel (not DFCO). It is not isolated to any cylinder. Bugs the hell out of me.. But, its only like counts of 4.. I have desensitized the tables tho.. I'm guessing that I'm seeing the car switch from the "Normal" misfire detection tables to the "Idle (Not Moving)".. Yay.. an epiphany.. I'm going to go check it out.

BTW: If pyro doesn't have a cam or verter then yikes.. something may be wrong.

^^ I do not (until next week) have a cam or converter.

Tell me more, Obi Wan Blade-obi.

Haha. Well, I don't know if DashHawk can do this; but you should be able to log current misfires for each cylinder. Check and see if it is isolated to 1 cylinder or bank.. Have you changed the spark plugs, spark plug gap or the wires? Do you have headers? Are any of the wires touching the header?

FWIW I had mine touch the header. Right at the 90 degree bend.. Not too too bad, but the wire definately had battle scars.. Surprisingly, it was this wire that measured the least resistance of the rest of the GM stockers.. 795 when the others were hanging around 810; a couple 820..

On a side note to this, being the dangerously-ocd fool that I am.. I wiped off/pointed to the spot on the header that the wire was touching when showing my friend the headers.. I had no feeling in that area of my finger for a long while.. I actually heard it sizzle a little. It wasn't too too bad.. Kinda like so hot its cold. Don't do this..

^^ The DashHawk can't do individual cylinders (that I'm aware of), but I can look through everything that's part of the ignition system. Can HPTuners log this info? If so, I can do it that way when I get a chance.

I'd been thinking about some sleeved granetelli wires and new plugs regardless, so this may be a good time to try swapping over.

And don't worry...I've already lost all the feeling in both of my hands. That's a wierd story involving AN/FO and too many hours of overtime.

Yeah hpt can do that.. Log current misfire for each cyl and see if its isolated to one. I'm at a god damn airport using my cellphone thru the cradle thru usb to get a damn internet connection.. 1 hour and 15 minutes left, woo fucking hoo.

Old thread I know.

But DashHawk CAN log misfires per cylinder but you can only log 5 pids. You can view 7 cylinders of misfire on the DH but can only log 5.

Yeah, I discovered this, and logged both...it was about that time I decided to purchase HP Tuners and do it right . I booked time Sunday Morning to calibrate the wideband and start tuning with it, so we'll see how it goes!

The DashHawk really does a good job with the exception of the PID record limit.

Getting the chart window formatted (stretched out) is a little tough to figure out but works good.

If you haven't done so, remember you are going to have to find power somewhere for this thing to run the LC-1 electronics and heater.

Did you get your bung installed?

Be careful not to kick the thing into calibrate after installed. It its not free air calibrated you will be in trouble
