I've been dealing with some tuning issues since switching over to the Holley Terminator X TBI.

The 1st issue I discovered was the learn table was not being populated if that's the proper terminology. While the data log shows it's in learn mode, it comes up all 0's in the table. I'm still trying to figure it out & it makes it hard to make changes to the base fuel map without it.

The second & last issue, I think I fixed it today. While I was seeing some weird things going on in the data log with close loop compensation. I finally tracked it down to faulty Manifold Air Temp Sensor. It would work at idle, driving around in the pits & in the shutdown after the run. It would also work for about 1 second into the pass. Then it would drop into some very cold temps & started getting low/high error messages. I pulled the connector off the sensor & immediately saw the issue. The 2 male pins were barely protruding & might have been rubbing on the female connection.

I'm pretty sure I have the MAT sensor fixed. We'll see if the learn table starts populating; I made changes in the Learn Compensation Limits Table.

While I've done a pretty good job of not running over 150 mph. Most of the time I keep it around the low 130 mph range. I have slipped up a couple times, got close at 149 something; I did go 152 mph ripping the throttle late in the run.

Anyway, I bought a parachute & mounting kit from Motion Raceworks. It's getting installed in early June & is well overdue, mainly for safety reasons.

Also, I have to get a neck restraint system, looking at the Hans.

The plan is to still keep the mph under 150 mph; it works with my racing strategy.
