Map rescale tool- enables utilisation of the entire map. (no more tuning for one boost level)

Map Calc- takes your Wideband AFR info and outputs a correction value for quick and easy tuning. Also includes a cell hit table to get rid of bogus AFR values.

RB"s love 12's :)

Sorry, a missunderstanding. (just a tuning aid guide) Every setup is different. From load point 11 onward I would tune anywere from 12.3 -11.6

I have currently tuned for:

Inj

1.6bar Max load point 14, AFR 12.0-12.1

1.8bar Max load point 15, AFR 11.7-11.9

2.0bar Max Load point 16, AFR 11.2-11.4

Ign

30% Toluene load point 5-10 +7 degree's

load point 10-20 +6 degrees's

I also have an excel spreedsheet with has a database that I use with Datalogit to cut and past Wide Band AFR logging and outputs a corrected map in reference to a Target AFR map. Looking into making this automatic. Will post up soon.

would you tune a rb on 30psi on 12's?

for a general customer no, for a good mate with a known setup.... quite often :)

many RB26 tuners swear by the 12.0-12.2ish rule a good example is page 94 of the current HOT4S mag (diatribe i know) well know and respected tuning house willall racing has a dyno graph up with one of martins tunes featured running 12.2ish on a 300rwkw GTR

I find I comes down to each individual injector/fuel rail/pump setup. The key is to get even AFR's between ALL cylinders. Once this is acheived, leaner AFR's can be run more safetly. I have the standard fuel rail....with upto 6bar of fuel pressure at times. Will be replacing it with a center feed item before retuning.

martins tunes...

hahaha what a joke,

Martin says wow it makes good power,

1 week later BOOM.

and im not talking about a stock engine.

read into that what you will but i wouldnt recomend uras advising people to take there afr over 12 when running over

1.5 bar. sounds painfully expensive when something minor goes wrong, like bad fuel or a broken alternator belt causing your fuel pump to slow down and you all know what happens from there. shit starts happening real quick once your over 12.5 heading to 13 afr while doing 7500rpm

Do you tune for a living DANGERMAN4??

we are not talking martins tunes alone here, it just happens to be one of his... many top level tuners delve far leaner than 12 and 12.5. look at le mans cars etc

i also plainly said on cusomers cars they will get the plain jane tune, mates though always get the more agressive tunes as thier cars are well know by me therefore i am more able to exploit them safely..... never ever lost or hurt an engine.

my advice is forget the centre feed rail idea. use the centre port for the reg and have a twin feed (1 in each end). from what I know it's a better way to do it. just split your fuel feed into 2 after the fuel filter. :P

Roger, Roger..this is definately an area I haven't had much experience in.

    • You'd want to cap off the re-entry back into the dump too. Just something flat that can be held on by the Vband.
    • Thanks for the recap Matt Z. It was a great day out and I know you have said it already, but we couldn’t have done it without the volunteers.
    • Couldn't agree anymore, massive thanks to all that came by, helped out, or those who just wanted to talk cars. You are the community that make this such a great car club. cant wait for what we have planned for the future
    • Looking at the photos, you could easily just drop this pipe and dump into atmosphere  Just 1 or 2 quick hits for data acquisition - if have a heat shield material and/or sheet metal, maybe just use wire/metal cable ties and attach it in a way to deflect heat from melting nearby wires.
