Message to critique a bin without Dyno/AF readouts unless it is really aggressive. My current bin is running the JDM timing and with
Shell Vpower 93 octane I get no pinging at 15psi.

The problem is every car is a little different it is not possible to say anything other than it looks OK safety wise.
If any one is more specific than that without feedback from
the car they are guessing where yours is concerned.

Read the forums at [ http://ecu2.forumwise.com/ ] they still have some activity. Be careful with timing and try to get around 11:1 A/F at full boost.

I tried to code a good tune without the dyno or A/F feedback and did OK for a good safe tune with no lean spots and no knock. But if you want to make power it it gets unsafe really fast unless you can see what the A/F is doing. I finally broke down and bought a wideband and fitted EGTs.

I did not expand the maps and so far have not needed to. Map expansion comes at the cost of resolution. With 370cc injectors I would not bother. It is probably not an issue till you get to 740cc or so in my opinion.
