Stage 1.

Probably it could learn for better afr later. But your max engine speed - i don't think i could ever reach the same numbers as your 7591 - was it a kind of downhill drive?

I also noticed that my afr became rich with 1.55

I think that @shiv@vishnu did that intentionally to have a safer tune for all of us.

Hi Ondreiko,

It's straight flat road and I did this log after clocked about 100km+ on 1.55B rom

I noticed that my 1.55b tune is also richer under wot conditions than 1.42. It actually puts it back inline with the stock tune, as far as AFR is concerned. So

from me!

Hi!
Then how did you get that 7591RPM?
Some mods that i don't know about or did you modify your tables for higher revving?

Just to compare heres my WOT 1.55 log
http://datazap.me/u/ondreiko/010214-...log=0&data=1-9
Same G-series (A00G) and same 98 octane. But it is winter here

Changing the RPM Fuel Cut can do that. This is the Shiv set limit. Mine is set to 7650 and I have seen it as high as 7630 before in the logs.

Strange, mine is set to 7600/7550 on/off but i don't reach that limits during my wot pulls - have to investigate why when the roads are dry.

I usually only see it in first gear. Mine is set to 7650/7550 on/off and it rarely breaks 7600 RPM.

Are hp/tq rising upto your 7600 or dropping earlier? Whatever gear it is.

FrsDuke · 02-07-2014, 12:49 PM

His soft rev limiter is probably progressive so conditions will impact when it tops out. Better to be 50-100 rpm short than it would be to sometimes over rev I would think.

Shiv@Openflash · 02-07-2014, 12:51 PM

That is correct. Since we implemented the soft rev limiter, torque will fall off 50rpm shy of he max rev value. So it will take a few seconds to hit the fuel cut from that point on. You would have probably shifted by then

Read what the guys are saying below. I mostly did it because the is a slightly more noticeable (but not obnoxious) feel when on the limited. I noticed a few times where I was in part throttle and on the limiter but couldn't feel it because it was so smooth.

Hi Shiv!
This is probably the case - i do not like hp/tq drop and shift before it happens...

my average highest value is about 7400 rpm in logs.

Ondreiko · 02-07-2014, 01:28 PM

And i have one more doubt with my ROMs definitions - they are MILES and FAHRENHEITS in accordance with RomRaider tables - please confirm if it should work correctly with my metric car and ECU?
Or is it just RR.xml definitions feature?

Seems like my AFR dropped from 11.9+ to 11.2+ with more richness after comparing 1.42B vs 1.55B
