Yeah this one is a little funky.. I'll give it a whirl but I'm not selling my MBC just yet

You can run reasonable safe using just narrowband sensors, since the stock computer will take over correction in closed loop operation. You WILL need a datalogger to see trims though, and watch knock. I'd run wastegate boost until you get a wideband. But there are many cars out there creating quite a bit of power only tuning using narrowband O2 sensors. Don't get me wrong, you WILL need to tune your car, not just dial in an injector size. You just don't have the option of using the wideband to help you.

I want to get all of the in engine stuff out of the way, but I'm considering holding off on all the gauges needed for tuning, if i can still use the larger injectors safely. For the injectors, i at least need a MAFT-Pro, but my question is: If i just get a maft pro, and dial in my injector size, does that work well enough if I keep boost at stock levels? I understand that if I really want to put power down with more boost, i need a proper tune, but does the Maft-Pro work well enough to let a stock car at stock boost run the same with larger injectors as it would with stock airflow metering and stock injectors?
This new engine will be my baby, so if that's not ok, just let me know. Concievably, if a device really did exactly compensate for increased injector size, things should be just as safe as stock (at stock boost), but if there's more to it than that, I don't want to half-ass this.
Thanks for your input.

I installed my IAT sensor in my DN Y-pipe today, the welding is a little ugly but it was free. I'll grind it smooth and polish it eventually.



I took a 5/8-18 stainless nut and then I tapped it to the 3/8-18 Pipe thread that matches the sensor. The 5/8-18 nut is almost perfect, the pipe thread was super easy to tap and didn't require any drilling, I just enlarged the threads in the nut. Then I put the nut on the end of of piece of threaded pipe and used a lathe to turn it down to till it was round with a small step to make it easier to weld



This is what I wanted, the smallest intrusion into the Y-pipe, I think it came out great

Excellent.

Aux stuff is zero'd out


I know the PSI start is what makes it spike.. I have it up that high so that I can get some kind of boost out of it at all. Like I was saying.. it spools normal up to about 6-7psi, and then won't go past there.. then all of a sudden at about 5k or so it starts opening up.

keep the gain low for now, the Pro works a little differently than most of the EBC's out there.

Read the instruction manual, as there is a good explanation in there and in the solenoid instructions.

raise the Start DC% until the boost comes up to where you want it, and then tune from there.

Keep raising the start DC until the boost goes where you want it.

Ok. A wideband would really help though it seems, right? I was also planning on getting EGT and a matching boost, i guess i could keep my mech. boost gauge for now, and skip EGT. How helpful is EGT with a MAFT-Pro, anyway.

What gauges do most of you have?
-Taylor

[Highboosted]

EGT doesn't allow any more usefulness with the Pro (besides logging it), and I didn't bother with it because the EGT's are a direct relation of exhaust restriction/boost, timing, and AFR, if you keep those reasonable, your EGT's will be also.

My wideband is the only gauge I have added to my car. I don't even run a boost gauge anymore. I will get a boost gauge when I replace my center 3.

[Maximal]

I'll agree that an EGT gauge is close to useless to tune with but it's a good safegaurd to running too lean. I always try to keep an eye on mine when messing with stuff.

Good to know, i just ordered a MAFT-Pro with speed density and boost harnesses and sensors. I'll get my wideband from a friend shortly.
-Taylor

[FaceGarden]

Oh, and i contacted boomslang about a harness. $139+shipping... so I'll be gettin one of those too.
