Just figured if he was at high rpm no boost he wasn't looking for power
then again if he's at high rpm no boost due to being in the middle of a turn I could see why you'd need power to spool the turbo quickly once back on the throttle

Couple of interesting things to come out of that link. Firstly how much boost those guys are running on pump gas. High 20's where we see people freaking out when someone says they go to 19psi for example.
Secondly how the moderator gives the guy a warning for bad grammar. Funny.

did you MASH your foot ot did you "roll" your foot? You added fuel pressure and reduced fuel to the burner to make it a better cold start daily? Need to put some fuel in the wave crest and bring the trough up a bit to level. Don't roll your foot if you did, mash it down so the TPS gets off the part throttle maps, just a thought. Track car is alive - hadn't started in a year and half - new starter, turned over 4 times and lit off perfect.

Anything over ~60% throttle will kick out of the PT maps and into the WOT maps... Any boost and the DME will go to the WOT map as well. Only think mashing the throttle will do different is the enrichment response (very short burst of extra fuel).

Here is o copy of my AFR. Not too bad as a guidline, but could be smoother. Loged with zeitronix

Good to hear, Ski. Keep me updated if you take it to the dyno with the new setup. All of the data in the graph was at WOT. The "roll on" is pretty fast, just not a "stomp" - I'll post another run after the changes - looks much better now....... Yes, we did add Fuel pressure to make cold start better.

Ski

yeah, but those 65# fuel injectors will give a very good shot of fuel at a bit higher rpm if you mash the throttle around 3400 rpm, they used to take the car down around 11.8 but Tom has had to re-tune a bit for PA colder weather and he uses my old steed as a daily too.

Too lean for me when I was using MAFburner I would stay closer to the 12 on a/r on boost and that spike at 14 is defiantly not helping you either.

I gathered it was in reference to pump gas as most were posting about mw much timing they were pulling out to run those high levels of boost.

Here is the latest datalog after a few changes to the curve.
Should be good to go.

951_RS

Looking a lot better!

Rogue_Ant

Definitely looks better. What RPM do you hit your set boost?

brrgrr

Boost hits max around 3500 rpm

Rogue_Ant

Looks good - I would make it just a bit richer when you first hit max boost.

Is it possible to transpose ZT2 datalogs into a more universal format like this?
