102RON Racing fuel

[viceroy]

Will this hurt my 172?

 

[tonykart]

no gains no hurting at all. It will bring Zipp in standard car.

I currently run 93...we dont get 97 or 98 but I can get 102

 

[tonykart]

adjust ecu to amount of ron and you will see improvement in output power.

 

[viceroy]

How do I adjust the ECU? reset it by disconnecting the battery?

 

[tonykart]

Djeez NO, you have to let it install by a firm like superchips(or DIY if you know what youre doing).

gains approx. 10 bhp

can you not advance the ignition?

hmm yes indeed...anywayyyyyyyyyy

Viceroy, stick the 102 RON in, dont expect miracles as theres more to fuel than RON ratings. You should get an improvement though.

The ECU is more than likely the same aswhats used over here, these daysd most chips tend to be ok for 91 ron +.

However tio get the actuall benifits disconnect the battery for an hour or however long it takes for it to lose its learned settings reconnect and drive.

It will run at standard map in which there is no pullign back of timing etc, you may even actually get the 172 bhp.

However when you go back to the crap fuel it may pink for a while but it will adjust to the lower RON fuel.

erm...where did my last post go?



ps...thanks for the info Chris

Sure go for it.

Ron, this is the rather pansy test they do, MON is much more applicabe to your needs, but the 172 will periodically check and alter the max ignition timings.
