Relentless Gets EFii upgrade
 

I have been so impressed with testing EFii on several customer Titan engines, I decided to go all in for Relentless NXT this year. I can't wait to be able to manage the fuel with the precision of this system. Added bonus, Robert was able to program ECU to automatically manage ADI during race. This will greatly reduce the workload while chasing Race 43 this year...:D

Protech converted the stock induction in my GTSIO race engine.

Kevin,

I love the experimental work that your doing! I do have a couple of questions. Is there a reason in this setup that you didn't go with a fuel injector for each cylinder? Or are the two injectors that are in the picture for the ADI? Also does this setup have a mixture control?

Thanks,
Brian

Hi Brian,
In the pic, you can see the ADI injectors (Anti Detonation Injection).
There will be a gasoline injector on each intake tube.
You can also see the Throttle Position Sensor, and Intake Air Temp sensors.
Mixture control is automatic, though the pilot can modify it if desired.

EFII on GTSIO
 

Here is a pic of some of the other parts involved to set up the GTSIO.
On the left is the crank trigger and trigger wheel. These go on the front of the crankshaft which is accessible under a cover plate under the propshaft.
On the right are the magneto block plates. These have Teflon bushings that locate the accessory drive gear and shaft which remain after the mag is removed.

Thanks for the response! Any chance of installing one of these on a 9 cylinder Rotec engine, like the one on my RV-8? How difficult would it be to do both the fuel and ignition?

pics of the plane you are putting this on?

Look at his avatar photo.

Here is a shot of the plane from Reno, 2008.

This is the Relentless NXT:

Ed, I believe the actual design is a Nemesis NXT------Kevin calls his plane Relentless.

Second generation of Jon Sharp's Nemesis. The original raced Formula 1, as I recall.

Can't wait to see it in person....
