The AFR line is *very* flat throughout the range.
Yer killin me.
What constitutes 'desired'?
I'll turn it around, standby...
Nice smooth AFR line looks about 13.2 little twitchy at 2k-2500
Ok, thanks, Bud. Not knowing any better, I just wanted some independent verification that quality work was done. Being very new to this, I feel like its easy to get hoodwinked.
What you WANT the A/F ratio to be is the desired A/F Ratio. Those are the numbers you place in your A/F ratio map using a Laptop.
But even though you may WANT (or enter) the A/F ratio to be a certain value, when you check it with an Infra-Red exhaust analyzer it may be something else. To correct that difference between the desired and actual, you must modify your V/E map table.
The V/E map table is the volumetric efficiency table or how well the engine is an "air pump". The better it can breath, the higher the volumetric efficiency.
Hoop!
it is .. one reason i asked if it was motor city i know couple engines that melted down from there
Desired for me is a motor that runs well, cool enough, and that I get a reasonable boost in performance for my money. The improvement in sound I can verify is terrific. Many complements from the neighbors. . And the V&H BSS look great too.
