I've never been a fan of boost by MPH, prefer by gear -- for the reason, if I'm at 45mph, I could be in 2nd or 3rd... I want the boost target of 3rd if I'm in 3rd... not the boost target of 45mph (which could be quite a bit lower).

What ECU are you using that you can't do some sort of boost control? Even ECUTek has it.. granted it's pretty basic.

I tapped into the can bus at the OBD port and it has a ton of info but I don't have a gear ind. I was hoping I could configure a channel on Ecutek and piggyback off the ecm or a can bus adapter for gear input.

I'm using a AMS 2000 PRO and Ecutek. I agree the Ecutek boost control is basic so that's why I went that way.... Plus I have control at the track for boost and power levels to tune the car to the track to do its best on a non prepped track.

To tell the truth I'm getting a lot of question on why I'm not using traction control with ign retard I just feel it has a slow response to ramping the timing back, the car just feel sluggish coming off traction control. That's why I use boost to stick the car and apply all it can hold at a given speed. I pretty much dialed it in using the software that came with the AMS. I like it but some day I will have to grow.......
I haven't played with the traction control it's in stock config and maybe I could dial it in to help with Ecutek but as of now I have not done anything with it

I didn't think it would be there. But RPM & VSS is, so you can actually build a very simple box to output an analog voltage per calculated gear based on RPM & VSS.

That's a very good boost controller -- but we can do everything it can, and more, with our boost control logic in the MoTeC. Even run your CO2 system (their solenoid for CO2 control seems to be the best on the market, very fast response).

Ignition retard based traction control is literally retarded. Tested it way back in the day, and it's one of those situations where "it works", but is actually quite bad. PID loop based TC is just as bad (too much error->correct). MoTeC's strategy is great, and I've built upon it. You can't even tell it's working -- you put the car on what the tire can do in each gear and you're done. No error, no correcting, no BS.

Here's a demo of my rolling anti-lag. Note, no wheel spin :P

Car's on E50 fuel right now, so just under 14psi max boost. I can target more boost in 1st gear still, but I wasn't going to screw with it for the demo. Halfway through the video you can see the "Boost Aim" is relative to my angle & lateral G. Some new programming I will be testing -- it would be nice to have a whole day at the track to dial it in (and anyone using it certainly can).

Dude you got this down way better than me... So what can I do with Ecutek and this AMS2000? Or should I say what do you suggest. A 5k stand alone from Motec isn't in the picture right now. Also what do you think of the AEM infinity??

I would build a simple Arduino based interface to read the CAN RPM & VSS data, then create a gear calc that outputs a 0v-5v signal based on the gear you're in. You can use that output as an input on your AMS2000. I can actually build you something like that if it was worth my time.

Honest opinion? We use them for some things where cost is a factor (and it's better than a lot of "other" ecus), but compared to the MoTeC, it's junk. Their strategies are shit, their datalogging very poor, tons of comms issues plague their Chinese hardware. They also do *not* support the FA20DI trigger pattern, and the likelihood they will add it is between zero and none. They also have no CAN integration for this platform, so nothing on the car would work.

MoTeC >>>>>> AEM.

Well I value your opinion very much and I will take your advice and pass on the AEM.... Thank you for steering away from a waste of money. I'm interested in your gear thingy that I need to get this boost by gear going. If its not cost prohibitive in my situation I'm game to try it. You can PM me with a price when you get time no rush. I want to get as far as I can on what I'm doing then build on that. I appreciate your help thanks... Also a bad ass anti lag map like that would be cool lol

Well shoot me an offer with what something like that is worth to you and we'll see.

I have no idea how to make one or even what it is, to be honest I can research it but to save time just let me know what I am looking at. lol And a ball park price too if possible. I'm going in blind here......

Interesting... this could also work for Ecutek (rear O2 signal can be the input to Ecutek and use it as a custom map?). What do you think?

It looks like a great TC solution.

I have one can bus adapter tied into my OBD port wiring a plug and play unit would be nice too that converts live data into a gear position.

Why? ECUTek already has a Gear parameter for custom maps.

Someone needs to let me borrow their Centri blower powered car for some R&D, we can do a boost by gear kit for those and implement similar logic

What kind of R&D do you have in mind?
