I need to actually make a video.  The process slows me down, and I've got deadlines, so video is usually the first thing I skip.

I get it, filming is easy for me, its the dang editing I don't like.  You were good on camera so I appreciated them when you put them out.

I love the plate and knew what it meant instantly!   :cheers:

Exciting to see how it goes, I think your spot on with the GM ecu this time.  Keep it simple sometimes is the best.  Still Curious what canbus issues you will have/solve.

Did you dyno at lower RPM at all?  LS engines continue to impress even decades later.  That is a lot of NA power.  What does it idle like?  Good to compare my street engine mild cam LS7 making 681 so your 60+hp more with a couples cubes less then mine.  I am now happy I am not giving up over 100hp for "minimal chop" I will take a 60 diff in a street car all day long.  That said this needs to be in a drift car or something!

Electronics / Re: Digital inputs on Maxx or any ecu confusion
« on: March 06, 2024, 10:03:34 PM »
With MaxxECU, I believe the digital inputs are expecting a positive voltage, like a 5V Hall sensor for example. If you want to do ground switched triggers, you can enable a pullup resistor in the software so that it can be ground-switched. You can use Analogue inputs also. https://www.maxxecu.com/webhelp/wirings-digital-inputs.html

There are a couple ways to expand your Digital Inputs beyond what's phyiscally included. CanChecked makes an IO expander (MCE18) that adds 9 analogue and 6 digital inputs over CANbus. It's a great option for things that aren't speed sensors (CAN is limited to 20hz update speed). https://www.vadpro.com/products/canchecked-mce18-can-bus-expansion
MaxxECU has a dropdown configuration for the MCE18, so setup is pretty easy.
https://www.maxxecu.com/webhelp/can-external_devices-canchecked_mce18.html

You can also add a CAN keypad. I have a Blink Marine 12-button keypad and love it. MaxxECU has the Blink features very well integrated into their software and make it very versatile. It's only 4 wires and takes up none of the ECUs inputs (all CAN).

The other option to save using physical inputs are User Outputs. https://www.maxxecu.com/webhelp/output_functions-user_output.html
User Outputs simulate inputs based conditionally on any data the ECU already sees. User They use IF statements to "turn on", and the User Output's status can be used to turn other ECU features on/off. For example, IF RPM>2000 & MAP<50kPa, User Output 1 = 1. If RPM  or MAP are less than those values, then User Output1 = 0.

A practical use of User Outputs to save you using Digital Inputs - You could use the brake pedal input (which you do need for cruise control) and TPS to enable launch control, rather than needing a button wired to a DIN. The example would be IF Brake Light =1 & TPS >90. Rather than holding a launch button, you could foot brake the car and it'd go into launch control.

Hope that answers more questions than it raises lol.
Wow that is amazing thanks bud!  I am actually following what you said very well. 

Is there a limit on user outputs?  That makes so much sense to me, in the Motec I’m having to use tables to make my if statements with different values on the axis. The user output feature you described is much better alternative.

I love standalones! Ha. So cool!

Electronics / Digital inputs on Maxx or any ecu confusion
« on: March 06, 2024, 01:37:08 PM »
I feel I am decent at wiring but still a newb and can't quite wrap my head around Digital inputs on a stand alone.  Specifically on the MaxxEcu Race version they list a ton of features under the digi inputs.  Like AC compressor on, AC clutch off, 4 different ones for cruise control.  On the physical wiring how do you do it with switches and to what inputs?  It seems like the ECU would need a ton of inputs if you want to control cruise, AC, etc.  I only see 4 dig inputs on the race ecu and 1 of those is speed.  So its not a wire for input ratio do you use some sort or switch box?  Or maybe I am over thinking it, originally I was thinking digital inputs are all the values available inside the ECU like MAP, TPS, etc etc. 

I ran out of inputs on my Motec and sucked when I needed more but that was wire for input ratio of 1 so it was easy for me to understand and I never used any digital because I don't know what it is lol. 

So just looking for a pragmatic example of how you used a lot of these with only a couple pins wired??  Thanks!!

Drivetrain / Re: Anyone swap 6th gear on magnum?
« on: March 06, 2024, 12:26:28 PM »
Sounds good, so technically possible in my garage if needed.  I was looking at that same 6th gear set to it would be both drive and driven gears.  Thanks!!

I’ve pulled that gear off a few transmissions.   It needs a good puller but isn’t that bad.

How about getting the new one back on?  Needs a press?  Tail section just unbolts and you have access to it right?

Drivetrain / Anyone swap 6th gear on magnum?
« on: March 04, 2024, 09:59:36 AM »
Looking to possibly swap my 6th 0.63 gear for the 0.50 gear in my Magnum close ratio trans.  From what I gather its in the tail section so access is easy, but I see a lot of people really struggling to pull the gear off and install the new gear, like snapping jaw pullers, etc.  Is this something that I should just take the entire trans to a shop and see if they can swap it?  Is there a removable part of the the 5th and 6th gear, and reverse area I could remove and then take that to a shop? 

Just curious if anyone has done it. 

Thanks!

The Lounge / Re: Longest road trip in RX7?
« on: March 02, 2024, 11:04:45 PM »
Perfect pics, thanks!

I'm thinking either there or similar location on passenger side. Where you have it is the same area it's mounted in the Camaro, if I remember right.

I like your push buttons, too. Very clean install.
Yup limited with the cable routing. Only so many places. 

The switches light up blue as well when  engaged.  There is a complete write up in my garage thread if you need help with the wiring.

Good info Exidous, thanks.
I've got a cruise box from a '98 Camaro, which is same year as my ECU, so wiring should be pretty easy. The box is surprisingly big and the cable from it is a fixed length, so doing a clean looking installation will be a bit of a challenge. Would rather keep it in the engine compartment, as I truly hate working under the dash.

Kinger, where did you mount your cruise box?


Wish i could have hid it more but I got lazy.

Here are the buttons

Kinger, I'm trying to decide the best way to add cruise control. Did you use an aftermarket setup (like Rostra?) or did you adapt stock GM stuff?
I used a 1996 caprice cruise module.  Then in the interior i wired up two momentary switches that light up when activated.  Buttons are mounted on steering column plastic. Very small and discrete. Couldn’t stand the look of stalks plus i have a removable momo wheel.

I did a road trip that ended up around 2000miles, it was right after the swap too. The mpg in 6th on the highway combined with the light weight was pretty stellar on the wallet filling up.

Wow where to and over how many days?

Do you have cruise control?

Yes!!  I added it within the first year.  Too many long straight roads here and same thing with my foot.
