TST, single miss and P0336
Well, after running the VA C3.2 for quite awhile without any problems I decided to try the TST. I was under the impression that most of the driveability and code problems were worked out. Installed the TST and started the truck up. Cool, no codes. I was cleaning up my tools and the truck was sitting there warming up and I heard it miss. Just once but very clearly a solid miss. Truck was just about warmed up so I went for a test run. Rolled into it hard on 6x3 and instantly set the CEL. Pulled over and checked for codes and had the P0336 that is so common. On the way back to the house I got the single miss again. Pulled the connectors, cleaned them and hit them with dialectric grease again. Second test run and in cruise down the freeway, you guessed it, single miss again. Horsepower king or not, if this is as good as it gets it's going straight back to TST!
Any ideas or comments?

Apparently, there was a batch of out-of-spec diodes used in some of their injector harnesses, creating too much noise in the signal. This caused an occasional miss just like what you describe. Fix was a new injector wiring harness. Food for thought.

Thanks for the info. After much debate I'm willing to send this unit back one time and see if it can be repaired. If not it's return city for me...

With just the TST set at 7x4 I slipped it just as it passed 2000 rpm wot. I'm getting an OFE installed at the same time as the B1-04. Since I don't drag race or pull the OFE should be enough for me to just tow heavy, which I do more than 50% of the time, and play hard on the street. The VA will be back up for sale if Mark can get this problem solved...

KSB1 with a special exhaust housing. On update. So far Mark is telling me I have the latest flash (which I already knew) and he doesn't know what the problem could be. He offered to take the unit back. Offered to run it on his truck but doesn't even have a test bench to troubleshoot the problem! No offers of letting me try a new box and no probable solutions for my problem. To everyone that is running this box without problems, thats great, but so far I'm not too impressed with the service or the product. Too bad because the power is awesome and my mileage was up 2.4 mpg but I won't use a product that makes the truck miss. Period.

Another thing you may want to check is your tolerance of the crank sensor to the tone ring. We've seen a bunch of these out of whack, and that will cause you to get a check engine light with the TST box. You want about 17 thou gap.

Greg @ tst told me about the .017" gap a while back and I just havent had time to mess with it. I do have about .026" gap right now and also have the same single miss and code 0336 occasionally, but always at 1100 rpm
last time I talked to greg he said to send my box in for a reflash before messing with the sensor (I dont have the latest program)
you say you have the latest program
I wonder if maybe the gap thing is more of an issue
Im curious as to what your gap is
and at what rpms are you noticing this
I also see your truck is an 03 like mine
when was the build date?
mine was one of the last ones in the 03 model year

or grind some off the shoulder to get it closer
no adjusting screw
pretty crappy set up in my opinion
an electrical sensor right out in the open for stuff to hit it and break it off
where was the innovation in that one?????
