Ok, I would say fueltech might not be ready, not the overall technology. It's based around drag racers, street cars which need more refined features. They are getting better, but still lack some basics vs other options.
I still think the idea is great. But my experience trying to get it to perform was less than expected. Perhaps a TS gate is a better option.
Im a bit bummed about it. Swapping the gates out is not an easy thing to do especially on RHD.
I knew going in on a new product was a risk, looks like I lost that bet. I’ll be keeping it, maybe the issues will get sorted in the future and I’ll put it back on the car.
FT550 is working great for all the other bits on the car. FT has been adding a bunch of features recently, only thing truly missing at this point is open CAN.
FYI, this gate has had problems with many ECUs from a variety of tuners, same issues with Haltech. I just happen to be talking about it, while other people are trying to sell their hardware on quietly.
By all means go ahead and say it's a FuelTech issue, and take the risk yourself. Sounds like you are confident enough to buy mine...
Sorry, I’m not trying to bash on FuelTech. It’s fine for lots of cases. But unless you got a lemon of a wastegate, which is possible but unlikely, then the FuelTech control or configuration are the only things it can be. It’s a simple motor with a position sensor.
There are some out there. You should call full race and see if they can connect you with anyone running it. Might be worth checking forums of cars that run small efr with internal gates often (Miata is a good example).
I'll see if I can bench test one and make it actuate this weekend and share anything I find out.
I have a bunch of e-gate cars running on Haltech all working as expected, turbosmart have done many revisions to their e-gates as the initial ones had issues getting stuck open/closed etc
. Fueltech has been working to try and resolve ongoing e-gate issues on their end but it is still on going. Whether that is specific to your unit or in general thats another can of worms altogether.
I mean I wouldn't expect full race to give much guidance unless you are using their controller. By using FuelTech, the only thing you are using that they actually have control over is a metal bracket. They might not have ever tried to control the MHI gate with a FuelTech either.
I didn't get a chance to mock mine up to test. Will try this week.
There's not much point in using the e-gate without direct control. I will lose a lot of the e-gate functionality with their controller. It's also $550 before taxes and shipping for the controller, and all that functionality is already in the ECU. A Turbosmart e-gate is cheaper than the Full Race IWG and DCCD controller..
Here are the e-gate specific settings I have to work with, set up with the last attempt we made.
I totally get not wanting the extra box, I don't want it either. I'm just saying I doubt they would be able to help you much if you are running a setup they don't have experience with and are just using their bracket to mount an OEM egate.
Where is the part that has your open and closed voltage settings for the position sensor? And is there a page with settings for max and min duty cycle? The page you showed seems like the front end boost control settings. I think what you need to figure out is the backend settings for configuring the gate.
The "back end" settings are on the far right. The left side is standard boost control settings / strategy, middle is e-gate specific control.
There's a separate, very basic, page for calibration. It will auto-calibrate by driving the gate to full closed, then full open. Or you can manually calibrate by setting the gate to full closed and then full open. Records the voltages. Neither work, because we apparently don't have the correct settings to make the motor move reliably.
And full race has said this e-gate has the same actuator travel length as the turbosmart pneumatic actuator, so the "not fully open" concerns we all had are null.

Having orders of magnitude changes and PID parameters across loads isn't going to help you at all, that's almost like making it open loop.
Is the target parameter or feedback measure boost and/valve position and or coil force? I would think you would want you PID values pretty much fixed across map conditions as a starting point and only tweak from there if there was a specific behaviour you weren't happy with and you couldn't completely eliminate from wholesale parameter adjustment. I swear some ecus make things worse by giving too much flexibility, you would probably be better of with single cell P I and D inputs than 3d tables.
That seems to be conflating base duty at conditions with proportional parameter too?
I will ask my tuner to look into it further. What sort of questions should I ask to see what the competence level is with PID tables etc? I don't understand it myself at all, that's why I've hired a tuner..
So far, full race hasn't given any input on any of the settings.
If you have any suggestions for settings, I'll give them a try. I will use a connector harness to swap out the e-gate for a MAC valve and dome pressure sensor. That will let me unplug the pneumatic stuff and play with the e-gate without hacking up the harness. I would love to get it working, there's a ton of benefits to an e-gate if it functions.

Sir, this is an RX7 forum, not a church.

I probably couldn't do a Laplace transformation to save my life now, haven't played with anything similar software interface or hardware wise myself.
Just so it's a bit clearer for everyone at home does 0% target position mean closed valve or is 0 half way open and it's +/- to go to travel extremes?
To add confusion a lot if ecus use different PID scale numbers.
There were a few basic guides for generic PID setting and boost control specific you could find by Google searching a few years ago. May be worth asking in the guild of efi tuners Facebook group if you use the platform, may well be someone who has already done it with that ecu.
I'm guessing the motec videos, Haltech page and the HPA tutorial should give you a start.
100% is closed on FuelTech, 0% is open. It sat at 0-2% on the dyno, wouldn't move.
Bummer about different ECUs using different PID scales. I need to get a FuelTech rep to log in and see what's going on. Should have some time later this week to see what we can do. It's an OEM Honda gate, maybe the Honda guys have this figured out..
The FuelTech USA Facebook page is really useful, I should post up there. Gotten a lot of help out of the guys there setting everything else up.
Car is hilarious to drive though, power ramps up pretty sharply as the revs climb and the wastegate gets overwhelmed, feels like an old school turbo. Funny thing, I wanted an open wastegate mode for normal driving, seems like I'm stuck with that for the time being. Also found out the minimum boost it will hold (0.9bar) so I know I have headroom for a larger downpipe lmao this car will never be finished.

this is off topic, but my car was more fun when it was like this too. mine was in the 2500-3200rpm range, so hilarity was available all the time
