View Full Version : Spark modifier, any use?

Ok after reading quite a bit on ls1tech from people who swear that pulling some timing at high rpm/vss helps power, perhaps due to air resistance putting an increasing load on the vehicle I was wondering if a VSS Spark modifier table might not be a good idea for a future COS?

MSD sells products to specifically deal with this and plenty of guys vouch for the gains. Seems like it would be a fairly easy add in.

Ross/Anyone any thoughts or comments?

Anyway from what I have seen if there is just a sniff to much advance at the top you get KR which will bring the spark scaler into play which will reduce the timing at that point anyway.

I have logs at 200 plus km/h and have not really noticed anything like that.
Next time I get a chance I will see if its worthwhile. Of course at 85kpa atmospheric it might not work that way.

Such a table could be added in, but, I'd like to see some proof first of the theory.

Cheers,

10 4, will look for some empirical information.
