wondering if this timinig is too low for cruise/low loads area or is it ok ?

 

Way too low and hopefully that's an E85 map due to the high timing. If that's a pump gas map = no bueno.

Cruise area's should be high 30's or low 40's FWIW. What's your peak load you're logging?

 

not E85, it's on 98 RON
hitting 240 load, @ ~ 1.1 bar
its an Evo3

what can cause that low cruise timing ?

 

So you're hitting about 3-5* at peak load and hitting 14-16* up top? If you don't have knock, then more power to ya, just seems like a bit more than what normal pump gas can take

I see you're running low boost- that's probably helping with controlling the knock.

 

hitting 2-3* at 3500-3700 on peak load and yes, 14-16 up to top

xperiencing knock mainly on spool-up and at low loads

 

Bring your cruise loads back to normal 30-35 range maybe

 

I've been helping Stunt with his map for a week or two. That's what I did as soon as he sent me this map to look over.

 

I don't know how or why you put your timing map like that. I sent you a rom that was decent for your setup. All you had to do some logging to tune it to your load ranges.

 

deee! duh! deee! /\

 

ok so here is my first atempt at a e85 map. this is based off my 91octane map and i have not yet run this on my car, i want some opinions first!

 

Help!

 

Not familiar with tuning E85 but it looks alright to me, might want to back down 1 or 2 degrees at peak torque to start with just to be safe.

 

check your timing at idle with a timing light

 

can incorrect base timing be the reason of symptoms above ? meaning only on low and mid rpms ?

 

Here's my timing map:


Here's my dataloglab dyno based on the tune:
