Al, I tuned my mail-in Dynoflash with a Innovate WB O2 and datalogger. I just installed 272s and Walbro 255.
The AFR is 11.0 (+/- .2) all the way from 3K to redline. It seems like it's pulling time around 4500-5500rpms.
The runs was done with pump gas (91), in 3rd gear.
It was about 90F, 20% humidity, 500ft (msl) elevation. Boost set to 20.5 tapering off to 18 at redline.
Cams set with stock cam gears.
This is the raw data. EGT never went above 1550F.

The Dynoscan read 329hp/294lb/ft.

 

Bishiboy - I dont have my records with me - was your flash for the CAMS ?

The timing s nce and smooth - should be runnng good - but a lttle low - you could prob pc up a few more whp with a bit more triming - although on 91 octane a custom tune is the best

decent whp numbers for 91 octane though

 

The flash was done before I got the cams.
Do you think if I add some fuel between 4000-6000 it will help with timing?
I'm coming to see you in LA on 10 Apr. This was just to get me by until then.
I'm putting in 680CC injectors this week too, (this is just to prepare for the future turbo kit).

 

Just as I suspected

You can either send it in for the CAM ign timing map - or just wait till the 10th

Your going UNDER the target on the load refernce on the ign timing maps and running too low a timing

Easy to fix

 

I'll wait, thanks

 

Your timing is low man. I remember when we tuned it that day you had 14 degrees of timing from like 6000 to your rev limit at 7800rpms.
