Interesting, and makes perfect sense!

One of the main reasons that I went for the Blitz is that it has the ability to map boost either against rpm, or speed.

So far, I have been experimenting with speed related boost - less boost in first and second (where lots of boost equals lots of wheel spin), and progressively more as I get further up the gears.

However, I am most interested in the mechanics of the midrange higher boost levels! I had not really given much thought to mapping the boost against RPM. I will play! The SBC has a rather neat dual solenoid design which so far seems to do a pretty good job. (one of the better things to arrive from Japan!). The amal valve has been carefully filed in the garage under "not to be used any time soon!"

My chip currently limits at 28psi, and I try to keep mine to no more than 26 at any time (for fear of leaning off). The mechanics are reasonably sound on the car, but the fuelling could certainly do with improvement!!

Once I have a better all round system (ie bigger injectors, and better control of such injectors), I will look into mapping the boost to the rpm, with a view to higher boost at mid range rev, and backing off at the higher range.

Cheers!

PS - Stu - have now sourced a standard L8 ECU! Let the shopping commence!
