Revo Settings help

[ktlstar]

Hey all,


So i am currently stage2+ which was set at B9/T5/F5

I am using 97ron at the moment and these were the log. I then went to adjust to 9/5/6 then 9/6/5 as shown on pictures... please could you advice what settings i could start with ?

9/5/5

9/5/6

9/6/5

As you can see im getting timing pull (alot) on 9/5/5..

[PDT]

Try 9/5/4

[ktlstar]

Thanks PDT... Will stick some 99 tonight and will go from there!!

If timing pull is better with those settings add some timing.  I.e 9/6/4

If that is still ok go 9/6/5

Stuck in 99 ron fuel and went out and did some logs on the 9/5/5 just because now i put 99ron. The results were much better then using 97 so i didnt think using 9/5/4.  and i thought i try out 9/5/9  (B/T/F)

Made a difference with good fuel :)


959 logs,




955 logs



I got to admit i think that 955 felt alot stronger in mid range! But what CF looks better between the two ? I am looking for one without to much timing pull i guess, but am i doing the engine any harm fueling it out to 9?

Heres 9/6/5 i also loged to see if i can get more power out of her... seems like i dont hit the 0.8 anymore from advancing 5 to 6.




This definatly felt more alive in lower end (wheelspin lol)

Does this setting look safe?

I would drop back the timing as your CFs now look too high.

Its back to 9/5/5 now - abit of 99ron changed it dramatic.. So lesson learnt not to use 97..


If i was to want 0 timing would i need to drop timing to maye to 4??   What you think of 959 log?

The ecu needs time to fully adapt to the new fuel so I would continue using the 99 RON fuel with your present settings and relog after about 3 tankfuls.

  thanks, will do.

Timing pull is hard to describe, but the numbers are basically an indication of how many degrees over-advanced the ignition timing is.

Ideally you want around 1 degree of pull on every cylinder throughout the entire rpm range. This means that you are slightly over advanced, but more importantly not under advanced (or too retarded  )

If you have 0 timing pull then you may be underadvanced meaning you are not achieving peak VE (volumetric efficiency) or in simple terms the fuel being used, is not being used to its maximum potential.

Getting maximum VE isnt easy on a production engine and requires individual cylinder injection and timing adjustment, this allows you to tune each cylinder as an individual engine.

On 9/5/5 you are pretty much there 

9/6/5 has a nice spread of timing pull accross all cylinders but slightly too much, meaning that although 9/5/5 has some 0's in there, you are as close as you will get to being spot on with a Revo tool. Fuelling is nice and safe as well.

[ktlstar]

I appreciate your views PDT... I think to say 9/5/5 it is then.

Sorry to crash, has been interesting... Have you tried v-power

Why do revo say timing 5-7 for 97-99ron fuel and normally see settings on 5...

Is B8-T5-F9 sound about right on stage 2 with a standard pump using v-power?

Cheers,
