I should be sleeping... but I punched in your rpm timing and vacuum advance and boost retard numbers and holy !!! I'm really getting somewhere now! BUT, At about 6 lbs. it starts missing, like it was running way lean, but my afr is still about 13.2:1. Would this mean I need to retard timing a bit more at the higher boost levels?

I'm interested in what you think about using your timing values for my set-up. I am just getting used to the sds em4-f, or should i say, I'm just learning about MP vs. Fuel Values And MAP's ... and stuff. I have an 86 rtec with a new engine, 315cc injectors, 3 bar map, msd dis-2, wms wideband, T3/T4, intercooler tial BOV, delta wastegate, ...and stuff... - I just got this thing running a couple months ago and have slowly been straightening things out, to the best of my ability... I'm slowly getting the hang of how things work, but still have m.p. fuel values that aren't at all like the examples in the manual. I started by adding 50% to all the fuel values listed for the 20r turbo based on a suggestion. now I'm getting it close, but still have work to do. I have a ET of 206 n.o.t. - is that about right? what injectors do you run?

Thanks for the timing info. I think I currently have no vacuum advance which may explain why it idles so rich. Around 10 sometimes. If I adjust so that I have some vacuum advance then maybe I can adjust the fuel down. If I have time this weekend ill take a look at things and give you a call. I think for my timing I will take your map and add 1/2 of each value to itself. So for example at 1 I would have 1.5 and at 2 I would have 3 etc. That way at 7 psi I will have around 15 degrees of retard. I think I may be fairly close to that right now but its been a while since I checked.
