i just got my set up on the road..lsvtec,ramhorn garrett 60-1..81.5mm forged internals..im street tuning it now..i got the a/f between 11.5 and 12...7psi for now,till i get better at tuning...i have the base timing set to 16 degrees..and the ign retard to .9...is this fine?..or should i take more out for now?..im useing crome 1.4 with the timing fix added
just want to make sure..before i turn the boost up a bit more
thanks

Crome's timing number's really are not accurate. Do your self a favor & stay away from full throttle conditions until you are on a dyno & can monitor for signs of detonation. Honestly, I would suggest switching to eCtune, Neptune, Hondata :-P

 

you should be fine im on 18 degrees base timing on 9 psi you have alot of room to spare for power..

 

ok i have mine set at 16 degrees base and .9 ign retard..i thought that was pretty conservitive?..but i was just making sure?

im just using free crome for now...i might switch over to ectune later on...but i was just wondering if my timing was on the conservitive side for now?..or should i take more retard/psi out?..id like to street tune it up to 10-12 psi for now?
thanks for the input

 

on my st tune i did i run .75 retard and 180% fuel boost compensation. i had .9 like u said and it was too much retard for my setup but yours is prob higher compression so may be ok for u .. just make sure its not popping or detonating..

 

bump

 

well u didnt tell us what kind of fuel you are using...

do some WOT pulls on the highway, turn off the engine at the top of your pull, pull over and read the plugs. if u see signs of detonation try to back off the timing. if not give it a tiny advance.

this was my plan but i ended up doing the smart and right thing and hit the dyno

well worth the $300

 

im using 91 octane..i plan on goin to the dyno..i just wanted to street tune it for now and get the a/f flatened out....and was just wanted to know if i had the timing on the conseritive side is all,till i hit the dyno to safly adj it
thanks

 

bump for some advice

 

????

 

any advice for a beginer tuner haha

 

.9 should be a good starting point. just make sure u look at the columns after you use the boost table adjustments because if u make changes to ignition retard, sometimes the resulting timing numbers come out all messed up.

if you absolutely aren't going to a dyno, make sure you pull plugs after any changes and check for detonation.

 

okie..detonation will look like spots...or peper on the end of the plugs rite?

yes, looks like specs and sounds like popcorn popping. there's a write up somewhere on here about reading plugs. it's pretty good. i really prefer s300 over crome though.

 

post a screen shot of your timing maps
