So I picked up a set of DW1000's as my 550's were maxed out around 15psi with my current setup. I've gotten a map from FM that was based on their ID1000 E85 fuel map from Jeremy and from what I see, my map looks to be OK. I ran autotune on the car, however I had to adjust LAMDA values for the idle and warmup cells since the car barely idles if I try to go to 14.7 (I must idle at 13.4 or lower to be stable).
While driving on the freeway, I put the car in 3rd and cruised at roughly 5800rpm since the autotune works best when I operate in the area that needs tuning. The autotune apparently didn't like that, and put a massive canyon in my map from 640mmHg all the way up to 17psi between 5 and 6.5k. I spent the better part of an hour flattening that out..
A few issues I'm having, however;
- Loss of power at the low end (I'm trying to pinpoint it, but I was driving without a co-driver) -- This appears to bleed in with trying to rev from low RPMs, easier to do when the engine is above 3500 or so, below that the car seems to stumble a bit then catch itself and go.
- Some issues with severe spikes in AFR during boost, as seen in the included CSV, I managed to pull off 9.7:1 at 6700rpm @ 15.3psi
Now, I'll be honest and say I have no idea what the hell I'm doing here. The fuel map is fairly straight forward, however that doesn't stop me from having the issues I am having such as my lowend power loss. I DO NOT
want to blow another 400 on a dynotune session to run out of time before I get to the good part because I spent all the time fixing ****, I want this car running for once before I go to the dyno.
So, if anyone can take a look at my map and/or CSV and let me know if there's anything I can fix, I'd appreciate it greatly. If another log is needed just ask, I'll post one up ASAP. I have a track session and events coming up in 6weeks and the only local dyno shop that I have any faith in is booked 3 weeks out. I'm cutting it close.
: I am aware of my coolant temp and the heatsoak on the IC, I've got a 22x8x3.5 that'll be here Wednesday, and ducting will ensue Thursday. I need a bigger WGA as it's fluttering +/- 1psi at 14+psi.
