I found the issue with the timing. Burst knock retard. Apparently it anticipates knock even when there is none. Similar effect to the bias values I think. Looks like a proper VE table /...
More often than not, when a seemingly simple problem is complicated to solve, it is almost inevitably a simple solution. This would happen to me.
Bet you were glad to finally hear it fire off!
Thank you for the reply Fast355
I recognize you are a VAN guy and this is a half-VAN [pick-up]. JI recall the times my friend and I frequented the street races in Dallas with his Dodge conversion...
OKay Fast 355.
I am better understanding the spark timing scheme now and your comment about raising the tables in that area are jiving now.
If I am wrong here, please correct me.
The main...

I am not qualified to advise on the tune really but from recent experience, disconnecting the battery will reset a hard code 42 when a scanner will not reset. If it comes back without Tuner...
Copy that. I really had no intention of leaving it this way. I see the removal of the Spark Bias as a troubleshooting step not a permanent fix. I believe I have identified I need better fuel mapping...

Pulling the battery power reset the computer and all is good in the world again. Thank you for the gimme. I'm still new at this EST thing as you can tell I'm sure.
The Mask I am using...
Thank you for the reply Kitch
If resetting using the battery disconnect will work it would really make make day. I attempted clearing the codes using the scanner but it didn't even blink. it...
Thank you for the feedback stew86mcss396
I have at least attempted to do-so. I put AA in the same place I found $OD. Perhaps I misunderstood what I was reading.:doh: I didn't realize there was a...

Well. It started as a beatutiful morning.
Truck running good enough I felt like hooking up, doing some emulation, capture some logs, do some tweaking, life is good. SO I get get the...

I made the pilgrimage to our [mostly] local Summit Racing warehouse this weekend to pick up a DUI module and a fuel pressure adapter for the TBI. Sure is nice to...
Update
I had a chance to install a vacuum gauge. Pulls 15.5-16hg which fluctuates with engine RPM +- .5hg but not jittery like guides or shoddy valve lapping. Exhaust backfire seemed to get worse...
[Anti-seize works as an excellent thermal conductor...better than the white paste. The copper based anti-seize is even better.]
HA! Is there no end to the usefulness of copper anti-seize?!?
[Early TBI systems were designed with a number of redundancies. One of these is found in the ignition module. If the module is not in EST mode then it will very quickly ramp up spark advance when RPM...
Copy that. I increased the values by 5% last night and it smoothed out some. Throttle is better but will still bog/die if pushed too hard. Exhaust backfire seems to be gone though. I will tinker with...
Thank you for the reply Kilroy
Good call on the vacuum gauge. I may have time for that this evening. I think I have the valves set in their happy spot at the moment. Dad wore me out on adjusting...

No check engine light is a good indicator the failsafe/Limp mode is NOT active.
Question on the AE vs MAP: Does a larger value = longer time-on for AE? That seems to be the...

Have to say I am impressed you got those numbers from the TBI heads. Everyone says they are good for torque but HP not so much. You obviously took the time to get it dialed in. Nice. I...
Thank you for the reply Neukam
There are some morsels in there I was hoping for that I can check out no problem. Very helpful. Glad to hear there is some timing built into the module. It was...

First time posting questions here. New to TBI tuning in general. More of a tinker project than anything really. Trying to learn something new. Apologies ahead of time for being long winded....
First, my condolences to Eagle Mark's family and friends. It is clear from what I have read here in this forum he had both a superior intellect and the humility and patience to wield it responsibly...
