Xede MAF effects on timing?
 

I've been asking around about this but have gotten different answers. I'm running an Xede on my 2000 with an MP62 hotside setup at 9-10 psi. My wideband is reading lean at higher boost levels but I smell fuel.

My question is when I have higher positive MAF % on my map... does this mean I need to advance the timing to get a burn since it's seeing more load?

None of the supercharged maps I've been sent are even close to what I'm needing. Also, my load only hits up to 45 or so where most maps tuned to 70.

Thanks guys.

My load map only hits up to 45-50 as well. What size injectors are you using?

I had a notification that someone bumped my XEDE thread, I added a final map for 440cc's in there, you can try that and fiddle with the scaling value to see if you can get a more legitimate base.

I'm using 440cc's as well. Mine are from an RX8. I'll check out your map. Thank you.

I noticed you have a lot of negative values while in boost where as mine are positive. Is this because your stock ECU is used to adding fuel in boost since it's an MSM?

My stock ECU is not an MSM, it's standard NB n/a ECU.

The negative values are there because the 440's flow quite a bit more fuel at the same load value compared to the stock injectors, and I need to back the fuel off in order to keep the engine from flooding.
