I dunno but 25 bucks will get us a broken one on that well known auction site...

Maybe you lucked out! How does that module compare to the one I posted (make/model/date/etc)?

I am in the process of pulling more 12V for a garmin, radio, etc. Everyone says there are free slots in the fuse panel and that is certainly true. I thought maybe some pictures would be helpful. You remove the panel via the phillips panhead screws along the top and the front. I want to say...

OK I tore into the controller. Jeez coffey was not kidding about the jelly. Pics are here, they seemed to be too big to want to upload: https://www.flickr.com/photos/adventioneering/albums/72157661316728564 The Amphenol jack connects to a PCB which then connects to the mainboard with a pair of...

I totally get where you are coming from on the stock angle. I wonder if a new ECU could be crammed into the stock housing, nappy buttons and all. Could blink more intelligent codes with the LEDs already there, multi button presses for features. It'd be cryptic but hey least then you'd retain the...

Thanks. How does coolant make it into the turbo in this application, through passageways in the block along with the oil? Or does it only get oil?

First and foremost I just like simple. It seems simpler to replace the controller than graft another system onto it which talks to it over a data bus via a reverse engineered protocol. If you go the scanner route you wind up with two ECUs, a harness (which leaves you soldering up more wires than...

I woke up this morning and in a cold sweat realized it was probably the air charge. What threw me at a glance is it runs up to the radiator (the other way). Much easier to fix though, so glad to be wrong. Normal you are saying superman? Would you leave it be? Reason it caused me some concern is...

Popped the cab for a little PMCS and noticed this coolant hose on the turbo. It looks nefarious to me. Seems like I can just go cut a length of whatever and hose clamp it on, nothing special. Also noticed that the hose clamps on the very top of the engine, seems like they have been digging into...

20? There's only 2 data inputs and 5 relay outputs (3 if you have single-channel CTIS) that matter. You can add one data and one relay if you want to preserve the over-speed indicator, but I don't see that being a pressing need. As far as I can tell from reviewing their material the entire...

Hello!

What I was suggesting is building a hardware replacement for the ECU. I think you took me to mean building a hardware code scanner (which is also a laudable and practical project). What I am proposing is building a new combined ECU+interface that plugs into the factory harness and deletes the...

What I really meant was I think it would be an improvement to just set a PSI, maybe in increments of 5 or 10, and have the system come to that pressure. From my understanding, should be possible with what is already on the truck. Sometimes I just want a little more or less.

Good work, that looks awesome!

Oh I should say - failing all this I'll just build a new CTIS ECU from scratch. With an integrated LCD display it could show the PSI and allow operator control of the pressure (raise/lower manually) as well as end-user programming. Then it can just display actual human readable faults. Probably...

I can implement the interface without doing anything untoward to the NexIQ. Like I said they are providing one implementation of the protocol, but the protocol is well known, their implementation of it is not essential at all. Where having one comes in handy is that by having one (yours, mine...

Followup - I didn't see your other observation. No, it would not be normal for the ECU or the NexIQ to contain the terminating resistors. The reason being that they don't know how you have the bus wired in the application. What if you are connecting it to a bus with 4 modules on it? If they...

The bus needs to be terminated because it uses RF signalling instead of just straight voltage signalling. It's essentially an antenna. The terminators prevent reflections at the end of the wire which would otherwise arise due to the impedance mismatch at the end. There are two advantages to this...

OK thanks to the other thread about CTIS reprogramming I've learned this is the plug. I figure I can buy one of these, break it apart to get the barrel, and then install that in my existing plug without messing with any of my wiring. Still haven't searched the cab for it. In case that link...
