But this seems like one of the few controllers out there that can actually offer true boost by gear etc. Not some halfway attempt. Certainly isnt cheap though.
Such price would be part way into the price of a full standalone ecu that would do it too.

You would need sensors in the trans to send signals for each gear, it gets quite complicated, when it is not factory feature.

Motorcycles already have this feature built in the trans.

Just use a rear wheel speed sensor's output and compare that to the engine RPM. That's enough data to calculate what gear the trans is in.

And if you spin the tires it will not know what gear your in.

No, you just need a suitable vehicle speed signal and rpm. Then you tell the controller the gear ratios etc.

So all that's needed is a simple interface and a couple of wire hookups.

It's exactly how my ecu does it and many others do.

And as the trans already has such an output....wheelspin is covered. As you're measuring driveshaft speed which is directly linked to roadspeed and engine rpm via the trans.

Auto trans are not that easy. TC slip.

The aftermarket setup on my ZX-14 uses RPM and wheel speed. It seems to always know what the gear is.

Does your zx14 blow the tire off? Bikes typically wheelie before just spinning going straight so bikes can get away with that.

Ratios are usually quite far apart. So it would take a huge variance to fall outside for it to think you're in a wrong gear.
But yes it is a possible issue.

On that basis, you still have boost vs road speed as an option. Or dont use an auto lol

I didn't say it could not be done I said it would not be so easy or cost effective.

Please share your simple interface.

Usually wheelies as the NO2 delivery ramps. But I believe it still keeps track of the gear using software that detects it if the tire spins. It seems to have the gear right either way, but I have notice at times it gets lost if the tire spins. So it doesn't work all the time, just most the time.

Never mind. My ZX-14 doesn't have a torque converter to deal with. Wheel spin is not a factor but clutch slippage would be.

By simple interface I am referring to the software within the boost controller.

ie a simple menu where you enter gear ratios etc.

It is easy, but the controller I linked is certainly not cheap. To the point where it's value can be questioned when a full standalone ecu could also do the same and much more.

My recommendation comes down to the original question, Cost effect, Necessary or Not.

In this case not cost justified.

I agree, but was just putting it out there as an option.

Many controllers claim boost by gear, most dont actually deliver it though.

Since this was relevant to the AGP TT Kit installation, I thought I would link to this thread on exhaust upgrade implications tied to the AGP Kit. Would like to have an AGP rep confirm the recommendation, but it seems sound.
