Which one, primary or secondary? You can fully disable the rear o2 via EcuTek and run whatever AFR you'd like. If you disable both sensors, then you will be in full time open loop. You should be able to run any AFR as well, but the car will not be very flexible with minor changes and quite burdensome to run.

i guess my stock car before e85 ecu tune was alittle sharper and more torque at steering.
is my guess true?

In doing the flex fuel setup we have had folks ask for a more budget alternative, and the biggest cost issue is the evap harness. So we made this for those who are willing to dump the rear o2 sensor (i.e. if you run no header cat) and in buying dozens of these o2 plugs we're making the harness available for those wanting to a do a DIY.

Disclaimer: If you run power and ground from the rear o2 plug you run the risk of frying the ECU if you short the power from the plug. This is why we don't use it on our flex fuel kits (instead pull power from the fuse box) and only pin the signal wire. If you want power/ground pinned, please request the option on the order page.

You can get them here: http://www.moto-east.com/store/moto-...ness-ft86.html

They are also compatible with the 08-14 WRX/STI. Pictures will be added later.

Now with these plugs, you can directly plug and play a SECOND input into the ECU. That means we can make you custom maps for a WMI failsafe input, AEM wideband failsafe input, or really anything you can think of that goes 0-5v. We can use that voltage to switch to an alternate map, or you can even use an adjustable usb or battery powered voltage regulator to set traction control strength, boost control, ignition timing, fuel...it is unlimited what we can do with this. At the $39 price point it makes much more sense than the other harnesses at 150!

A quick update for those following since we've gotten some phone calls as of late.

RaceROM 8 is OUT! The good thing is the cold weather bugs and speed density transition are fixed. We've had the beta for quite some time but it was something we could use only on local cars. Newest RaceROM takes care of all those issues. We are in the process now of converting the base tunes using the new featureset, but unless you're affected by either of those you don't need the update.

Otherwise we've made some great strides in optimizing the rotrex tunes, and fine tuning the electronic boost control with the turbo setups. We'll be porting that over to the new maps later this month and that will be the default.

Here's a recent dyno run from our friends at Hux Racing with a c38 equipped 86 with our flex fuel kit. 373 whp at 13 psi!

Super busy these days that we don't have time to bump our own thread

But what the heck, here's what we've had brewing in the last few weeks.



443 WHP stock motor, JDL equipped GTX2867R car. Powerband to die for, 4000 RPM window of serious torque.

In addition to tuning, we do all kinds of installations and build engines. Here's a JE/Carrillo combo we put together with a MAP turbo kit GTX3076R equipped.

Yes, 527 WHP. That thing is an absolute monster. Can't wait until it gets the bodywork and wheels/tires finished so it can put the power down. And that was running out of fuel. Should be good for 600 if we can get some ID1300's in there. Then we can raise the rev limit to 8000 and get it a broader powerband as well.

Not to leave the NA guys behind, the other day we finished off a 195 WHP NA pump gas car. Not all are this strong, but this one was.



The dyno chart above is referencing a stock tune car, granted on a different day.

Really nice looking curve... what was the header/exhaust setup on this car?

That was a FT86 speed factory catted header, can't recall the rest. Intake was injen I believe.

Hits 59, down 59 58,57,58,57,56....all with 100% throttle. Would reallllly like it to sit at 59,58

Do you have our smooth rev limit or the factory?

Smooth.
