yeah, why would I sell it?

:inout:

19°

4k, 8psi.

4500rpm, 93 pump gas
17° - 8psi
14° - 12psi
12° - 15psi

I was hitting 21-22° at 12.5 psi at 4500RPM, probably have room for more advance

15° minimum, ~15 psi @ tq peak

brainy i'm around 17-18 at 12psi. no we didn't push it until detonation, but adding more timing didn't make more power.

hmm, looks like I can safely add quite a bit more timing, especially since I am running on 94 octane and 8.2 compression.

I used flyingmiata's ignition map as a base.

Awesome shit, guys. That's what I wanted to hear. My goal is to have two maps, a normal 12psi 91 piss-water map and a 15, mabye even 17+psi map once I get a water injection setup. I probably won't push past 275rwhp or so until the motor is built, but I think I can hit that number even on a small T25 and big boost as long as I can keep the intake temps and detonation down (perfect use for WI).

yeah, that was my problem...I also had a 2° retard (i suck) so I was closer to 19-20°

right now my targets are 20° @ 180 kPa; 18° @ 210; and 16° @ 230

I was still making more power as I advanced it, but the returns were starting to become dimishing, my fuel was also way off, so it will probably be altered some. KnocksenseMS is 85% wired up, so I'll be able to make sure all is kosher and ready for my real dyno tuning session.

Hmm, so why is FM using so much retard on their big turbo kits?

cuts down on "FM blew up my engine!!!11!!one!!!" complaints.

seriously tho they make it for bad gas and lots of margin of safety.

i'm still using FM's stock map..

That's OK, you can run 89 octane then. :rofl:

i advanced it 2 degrees, i think i can go a bit more.. i have no knock as far as the knock sensor sees anyway..

Ben and Brain, do you guys mind posting up a screenshot of your current ignition maps (

should be in my "why i think timing is important thread" but here:

Ben's should be in his "I'm squirting" thread, should look similar.


I have yet to do much testing of this table as I'm not currently driving it untill I get my LC-1 back from innovative. Then I'm getting on a loaded dyno to do some comprehensive tuning. But as is at 12.5psi, I had no signs of knock and the power output seemed butt-dyno friendly.

Thanks! how come you are running 14 degrees timing at idle?

My map is close enough to brainy's. Why not run 14 deg?

I thought stock was around 10 and was wondering if there was a reason for the 14.

stock base timing is 10, but without TEN and GND shorted, it varies. measure it sometime.
