either I missed the option for manual transmission or unchecked it somewhere along the way lock up works but it hunts between 3rd and od below 60mph

Anyone? Davew?

My tcc isnt locking up, I have copied the settings from the AMUR 87 G-R-V Van 5.7TBI 700r4v1.0 vin to my vortec bin and tcc doesnt work in 3rd or OD like it did before the swap. i have adjusted the...

well damn now I feel dumb, I was taking pics of the comments so i wouldn't have to keep moving the mouse while mousing over the parameters.

borrowed a moates cable, still need the resistor?

mechanically sure, tuning this efi...still learning. i adjusted it down to 800 with target idle at 700

Figured it out, there is a IAC idle C/L ALDL was set to 1000 rpm. IF a chip is put in ecm backward can that mess it up? @Davew?

had the truck idling at 600 rpm trying to make sure it was set correctly without the iac involved, reconnected IAC back to 1k rpm. Any suggestions where else to look.. I also upped the timing in the...

I think the vacuum is so high due to the 1k rpm, I saw BLMS of 90 before I tuned it, it was just smell it was burning our eyes.

I leaned it out at idle because it was so rich at idle that it fogged the 40x60 garage I was working in, I backed it out to break in the cam. Between cam break in, checking for problems and tuning to...

Ok thanks Dave.

I have correct the IAC issue it now reads between 15-18 steps while idling warm, but ti still idles at 1k rpm will not go lower unless in gear. I sprayed the base of tbi and...

I haven't had a chance to try the idle set procedure as I just got back and its sub freezing here again. When it warms up a bit I will try the reset procedure.

@davew do you remember if that tune...

added some fuel to get it to run in gear, took it to the gas station to fill it back up and noticed it was way rich at cruising rpm to and from the station. Multiplied the 1200+ rpm blocks on the map...

Stock iac and tb, clip on plug lines up with lock on iac

The issue with the IAC is what I am trying to fix, not sure what is going on with it. I changed the VE1 corrected table and got it to idle and start better but now it dies when i put it in gear.

Someone correct me if I am wrong on this

VE = base fuel map
AE = Part throttle acceleration MAP/Modifiers
PE = WOT fuel MAP/Modifiers

Here is the data log of the cam break in.

fixed shitty link

Quick video of it idling with iac disconnected.

Absolutely, was just looking for some place to start with it. Isn't wide band o2 and narrow band offline at first start?

It is this tune

hold throttle ope so it runs, working off memory here from snap on mtu2500
1475 rpm
MAP kpa 33
timing light showed 27* with ecm connected

I believe that is the one, won't know for sure till I get home. Thank you for finding that.

I have been searching for the post with the tune but cannot find it, I have it on a pc at home. It was one you said you tuned for just a head swap and removed egr, AIR and disable lean cruise so it...

Which would be better for cam break in stock tune or the tune Dave W. Posted for vortecs?
