ok i was told by a friend that the lsjs dont make much if any power over 25 degrees of timing....im at 31 with no kr and a iat2 of 150. its 102 out here in california now thats y its so high. can any of u e85 guys shed some more light on this i also have zzp long tube header catless dp. zzp 3" catback. and a ported and polished m62.

 

Your friend is right.

A lot depends on how the timing table is shaped. If you can get to 25-26* of timing your golden. Anything more and you are just causing extra stress on the engine.

Where are you running that much timing?

 

Up top....28-31 and zero kr

 

wow thats high 27-28 is the highest i have seen on my table for timing while on e
who is tuning?

 

up top 26* is the maximum you should go. mid range you can run lots more. I'm not 100% sure what i'm running mid range but i believe it's in the 40* range.

 

im tuning my self...i have no idle isues...cold.start is getting beter everyday...almost normal...and im getting like 22 mpg

 

What is your AFR?

 

9.88
wideband reads like 14.5-14.9

 

What is your AFR when you are running 31* at WOT? Can you post your timing table?

 

That's just normal driving right? What about at WOT?

 

i forget the actual number but 10.9-11.2 on my wb... I run nitrous that's why it's so rich...35 dry

 

oh lord

 

problem???

 

Yeah bro, I've tested all the timing I could but I lost top end tq along with some hp. The best I seen was between 25-27 depending on top end load ...

 

Have fun beating the **** out of your bottom end.

Just because it isn't knocking doesn't mean you're making more power.

 

27 is the max timing that is usable up top. on e85. other fuels vary.

afr is fine at wot.
