What say you, Graham?
 

Now that Graham has graciously joined our little group, I thought he deserved his own "stickie" thread. It would be great to immortalize some of the great insights Graham can bring to the understanding and background of the ZR-1 and LT-5 in particular.


I'll start off by asking this question.

Graham,
What did you guys do, if anything, to mitigate the "split blm" issue we run into when tuning. Seems that the tune is a compromise between left and right banks. It would be nice if they both ran more evenly. And it appears to be exacerbated, particularly at lower rpms, when using larger cams and/or having ported top end, heads etc.

So

WHAT SAY YOU, GRAHAM? :saluting:

Is this something you did not encounter?

Re: What say you, Graham?
 

No we did not encouter a major difference bank to bank at design release.

What complicates the issue is installing different injectors ie Accels, RCs, FICs. I don't suppose use of ethanol was a consideration at the time.

Re: What say you, Graham?
 

I nominate Ethanol as one of the bad ideas of all time in automotive terms and when used or let sit for more than a few days in any engine with a carb. especially, boats, et al. as well.
