102 RON fuel at the pumps hits UK shores...

[Moby-Dick]

is this as high octane as some of that racing stuff ( Klotz etc. ? ) I thought that was 112 ?

[Lowe]

Race fuel's normally about 102 - F1 cars use 102 RON

Cool blue is 106 ( and £3.90 a litre !! )

Klotz seems for vary from 100 - 118 (£2.36 - £2.92 per litre )

suddenly that doesn't look like a bad price - its on sale at the big BP in Milton Keynes...probably a usefull stop for chaps pootling onto Santapod

Or if you dont want to waste money you can fill up a fuel cannister thingy and pour it in when you get to the track.. - carefully timing it so your tank is almost empty when you get there so you dont dilute the better fuel with worse stuff.

If you're leaving it down to the management to alter the timing you need to be driving it quite a bit for the changes to be made.

bp ultimate 97 was a waste of time.. tesco 99 ron was better than optimax

And full of ethanol.

Unplug the ECU for 10 minutes so it forgets everything it's learned, hook it all up again, and drive it like you stole it. Sorted

Lucky you, mine doesnt work like that...

All rather dependant on the design of the ECU. It's not just gonna play with the timing then, it has to run through and create an entire delta table for the fuel mix again, set up idle... blah bla

1980's Honda PGM-FI for the win then

Not got closed loop fueling then? Gonna take about 20 minutes to sort itself out if it's lost the memory.

I have no O2 sensors. I have a fuel map and an ignition map which cover the entire range from idle to 8500rpm. I've got some other things to play with, such as limits, launch control, shift light, etc etc, but because there is no O2 present there is no learning enabled.

However, by adding an O2 I would benefit from this (the ECU hardware is more than capable and the B series engines that use the same ECU hardware use O2s and monitor their AFR in this way). You can even run a wideband through the ECU

Like I said... 1980's Honda PGM-FI for the win
