Looking for someone to look at datamaster file & give advice

[Fast355]

yep fast355 you were right. I may flash to that timing table you posted for the lt4 hotcam and see how it likes it.

The one I posted was a vortec truck with LT4 cam and iron vortecs. The aluminum head reverse cooled hotcam LT1 will want even more timing.

At the 95-100 kpa range I would run no less than 16 by 1,000 rpm and quickly start tapering up by 1,200 rpm, I would suggest starting with 34° total and having it full in by 2,600-2,800 rpm. Once you get upstairs over 5,200 rpm and the cylinders stop filling as well it will probably want 36-38° by 5,600-6,000. Keep your air/fuel ratio a little fat in the 12.2-12.6 range.

You could almost use the table I posted if you added 4° overall to it and maintained 4° PE spark through redline.

Fast355 anyway you could post a .bin for a hot cam car similar to mine?

First time really tuning so I don't feel experienced enough to draw a timing table by hand.

for example my car with a 210/220 114LSA wussy cam went from a lurchy shitty off-idle transition under light throttle to buttery smooth when i ran 27 degrees flat all the way up to 1500rpm.

a friends car with a bigass lloyd elloit cam did the same if i made it a pancake right up to 2000rpm. it still snaps your neck if you give it any sort of heavy throttle of course, and since it's a sports car and you never drive it there except when you first hit the gas, there's no downside to fuel economy or anything.

Are you saying in the main spark advance table run 27 degrees flat all the way up to 100kpa?

Im dealing with some stalling from a take off right now, which i think is from closed tps not blending correctly with my main table. my idle timing set at 34*, when you nail it, it kinda falls on its face for a sec and then picks back up.

also can setting "Individual Fuel Trims TPS%>0" all to 1 help with part throttle BLM splits?
I get about 8-5 splits in my BLM's, they are both below 128 though so I imagine this may be acceptable, especially given I'm in SD mode? I'll be switching back to MAF soon.

Looking back at some of my old tunes VE tables compared to the ones I'm running now the old ones were F*****. so its definitely made a lot of progress and the car runs much smoother now.

Steveo,
Looks like you have the double E stuff dialed, have you come across or know of any obtainable reliable 16159278 $DA2, BDBK, XDF stuff? Down loaded the stuff here and on the tunerpro site and am having trouble with live data. Dave @ Moates recomended trying to find the TTS Datamaster software as the problem might be isolated to the tunerpro.

Any help or direction would be greatly appreciated,
Axman
