High Octane spark table for an E40 that has a 2300 pd blower fitted.

[Force]

Just asking for some help here. I have a 404 cube Ly6 block with a Harrop HTV 2300 fitted. We have partially tuned the spark table but would like to do a compare file with another spark table as I think I have a bit too much timing early in boost and also maybe late in the high map area. Here is my tune. I am also going to retune it as one of the injector data tables is incorrect and am changing the position of the blower temp sensor. The ecm is an e40. BoostedLS2_NEW_TUNE_03 with higher spark change 44.hpt
Even if you can do a screenshot of a similar tunes' high octane table it would be great. cheers

You really should be tuning your spark table on a dyno... not by comparing it to somebody else's table.

the type of blow you have is instantaneous for boost and torque which is where you have your max timing/peak torque

lower your 2500-3500 rpm timing above 1.0 airmass g/cyl something like 10 (depending on your boost as well)

how you have the tune setup is a bit strange

your maf is limited to 67lb yet you have your car pure maf above 5K?

i would tune the E40 pcm on SD only and fail the MAF.

as mentioned you need to use a dyno to figure out your MBT
