Re: Mazda Cx7 2007 custom FMIC
You can basically acquire any FMIC for a 6MPS/speed6 and fabricate the mounting kit. The piping will obviously be different because of the different things in the front.

Re: Big turbo tuning with stock manifolds
My question is: Would anyone know how much I'm restricted by the stock manifolds? Yes, I happen to know. Stock intake manifold with the VTCS on: 450-470bhp max. Stock exhaust manifold: about 510bhp (I made 509bhp on 31.5PSI, and at 36PSI I was making only 525, and eventually cooked injector on cyli...

Re: MAF Calibration 101
i'm just wanting to confirm that we shouldn't expect LTFT's to go to zero or near zero after any amount of driving (without changing MAF calibration numbers at least)? Indeed, the fuel trims, both short and long term, are a measure of the momentary fuel correction applied by the ECU. If you manage ...

Re: Proper EGR delete
What do you think the reason is that EGR deletes seem to be something that many people do look at? and why do a number of companies bother making a block off plate/block kit? An EGR delete kit is required in several cases. When you will be in one of those situations you will know. Why do people do ...

Re: MAF Calibration 101
Honestly the way you ask these questions makes them impossible to answer. So what you can do is to find your MAF calibration in the "Share your MAFcal" thread.

Re: Proper EGR delete
question about this @Steve @ VersaTune - is the reason that EGR increases low load cruising fuel economy simply because the exhaust gases that it puts into the cylinders basically takes up some of the room in the cylinder and effectively reduces the "effective displacement" of each cylind...

Re: OTS tune for downpipe + CorkSport SRI
Are you suggesting my money may be better spent on a proper tune with only the HPFP and intake? I'm a little hesitant to add the downpipe due to the age of the stock turbo (140k miles), but another possible path may be just a tune for now and then a turbo + full exhaust once the K04 dies. What do y...

Re: OTS tune for downpipe + CorkSport SRI
You can run any base 91US/95EU tune with these mods. Make sure you upgrade the fuel pump internals before you put the new downpipe, for at least two reasons: 1. with a faster spooling turbo due to the downpipe sometimes the factory pump may not keep up with the fueling demand; 2. you can unlock sign...

Re: HPFP Pressure low after upgrade
Hand tight? I'm not sure on what forum you've read that, but you should remember how it was tightened when you took it off and take that as a point of reference. It takes a vice and a lot of force applied to a 30cm wrench, that's a little more than just hand tight...
