Pretty good times for my ots stage 1 bm3 18 M550i.

Can you see how much boost and timing the OTS map makes at 6000 rpm?

[SctsOut06]

That is good. I've got the same - 18 with a Stage 1 and best 0-60 I've gotten is 3.48.

I think I'm going to add the xHP trans tune soon.

I will have to get it on a dyno. When I monitor through bootmod3 it’s defiantly a little over 20psi at peak boost. I am confident I can get 3 flat or a little under and maybe a flat 11 in quarter mile or 10.9. I still haven’t gotten downpipes filters or intakes or performance tires. And no other major performance enhancements. I defiantly want the trans tune from what I see it transforms the character of our cars into a beast. I wonder what makes my car with a tu2 run those times already. Should I get the trans tune before the downpipes?. Mostly everyone has downpipes at least or jb4 piggy on top of the ecu tune. I would love to get some sponsors.

I assume that's with an E85 mix as over 20psi sounds like a lot for the TU2. Nearly 100% more boost than stock map!

Yep it’s e30 stage 1. And it’s a ots map. Shouldn’t the boost be the same for everyone ? I may be wrong on the boost. Just saw it peak there when I trying to log it. I need to get official numbers. I see you run good year run flats as well they are doing some good times You drive a 21 correct.? I haven’t tried the brake boost method yet. I saw you’ll pulled off the 10.99 quarter mile with your jb4 on map 6. I gotta get to a flat surface completely.although on 93 stage 1 I did 3.4 consistently but I had old spark plugs. Never timed quarter mile

With an E30 specific OTS map, I expect the boost targets can afford to be much higher. I would look at the Bm3 data log rather than the live stats as you can get little misleading boost spikes when the gears change and when you lift of throttle for example.

I'm sort of stuck in a strange place at the moment where using Launch control for the best 60ft and 0-60 results in the traction control selecting higher gears prematurely at a hint of wheel spin, thus screwing 1/4 mile times VS Traction fully off which is faster overall but slower off the line. I think I need some better tyres ultimately...
