Default Opinions on my Spark Table

Hey,

Just want to see if i can get some opinions on my spark table. Car is a 1991 1.6 with turbo. Running MS1, intercooled, rx7 460's, all the other supporting mods. I got my VE dialed in pretty good, 11.8-12 afr in boost, tuned up to 14 psi for fuel table but i drive with 7psi mostly.

I am wondering if my spark table is ok in boost, with 91 octane fuel. I added some timing to get a bit more power just want to make sure it is not too much for the fuel type i am using.

Thanks in advance!

The 230 row may be a little aggressive for 91 if you aren't using aftermarket lower CR pistons, but I have no experience with 91, only 93. Ask Vlad (18psi).

you can drop it about 2* 184 and 156 regions and trigger 11.8 and should be fine on track on 91

Couple more questions:

Would i be alright to just follow the retard 1 degree of timing for each psi of boost rule, that work for 91 octane?

Also would this map be ok for 94 octane?
