Jeff's DIY turbo build

I think its the maf readings, will try to do a maf map, but I only have "stock engine" live data from techstream and it doesn't show voltage of the maf, only gm/sec.

You should be able to see MAF in and out voltages in the FIC software. Did you clamp your MAF at 5V? I really think there are much better alternatives to the F/IC. I'm still considering an ECUMaster ECU. Have to do more research first though.

I clamped to 5v, it gave me a maf low voltage CEL, still runs ok, i think I need to add more fuel on the TPS map for better quick throttle response... I'm really hoping the fic can help make decent power safely...

The ecumaster seems like the way to go, saw a video on hpacademy last week on how to cold start tune using the ecumaster black, for the price it's the best standalone outhere according to hpacademy, check on YouTube...

I was thinking of buying a 2009 rs and eventually do a motor build on the 06, but now I'm thinking of buying fiesta ST and tune it with hptuners, seems like a more viable option.
Will keep my 06 project but will stay conservative with the mods, I'm not sure if I want to pour a bunch of money on the yaris anymore, so hopefully I can make this fic workout.

Yeah, the F/IC is probably really a bandaid solution. My friend in Oregon installed the kit with the F/IC in his Corolla. He swears by it. Says that it works flawlessly. I'm going to talk with ECUMaster again this week and maybe my tuner too.

If decent AFRs are the only safety net needed, then I'm ok in that respect, I guess. I added my water injection as a safety measure. I really want to remove the car's ECU from fueling inputs. Standalone looks like the way to go. However, did you see the EcuMaster Det 3? Apparently it can control injectors in batch fire mode. It is a piggyback, but if it could take complete control of fueling, it might be a cheaper option that the Black or Classic. Would have to do some more research there.

Haven't looked into the det3. I'd buy the black before the classic since you can do much more for a bit more money. I've looked at my aemlogs inj% and the fic seems to be doing it's job. Adding more fuel on the TPS map really helped. Will post screenshots later on.

Tell me more about this TPS map. I don't have one in my tune. I have a fuel map, but no TPS map. Intriguing.

TPS or maf/fuel map, depending on the load input you choose in the system options. Click the little graph icon on the top right corner of the fuel map "mouse cursor is on it" , to see the maf-TPS/fuel graph...


The fic seems to be in control even in closed loop, actually too rich for my liking, was seeing 13afr around 3k rpm 120km/h on the highway, will record with techstream later on...

I'm still experiencing hiccups sometimes, mostly on hard pulls, right after shifting, getting into 2nd or 3rd gear. Have to make fuel and maf adjustments on high rpm gear shifts.

Waiting for my wideband, the fic is great after all.

Btw I had a crankshaft position sensor code at 1st with z007 firmware, flashed it to z0100 and works great, only codes I've seen since are; maf performance and sensor1 bank 1 too rich...
