Injection amount vs E85

I must be reading your graphs wrong but it looks like it starts knocking then pulls 3deg but the knock keeps going up even with the timing pull? How much knock have you seen to actually put aluminium on the porcelain of the spark plugs in a piston engine? Cheers

Yeah you are reading it wrongly, so instantly it takes out timing then it re introduces it after a certain amount of non knocking cycles, then if it knocks again, which it did then it takes out again and it repeats.

Once you do allot of these as I have you can see that once knock starts the engine is 'hot' and it wont really like the introduction of normal levels of timing but each time it varies! so this is why the ECU manages it.

On most cars I do I let the LR take the engine up to its knock limit, its an automatic process and the ECU does a fantastic job of running each chamber to its limit ALL the time

Why not E85 + water meth? who would be crazy enough to do this? surely it cant make more power and be more durable? imagine indeed kuntz !

Later in the year I intend to run my existing setup and an E40-E50 mix. I'm keen to see the difference.

The only thing I'm still on the fence about is an upgraded intake plenum, I just haven't seen or heard concrete evidence on this upgrade.
