i would be down for one as well. integrate it in to my mega squirt set up.

While the display project is underway for my prototype, I'm posting the reliability test of the display.

It is a TFT, wide-angle IPS (in-plane switching) display. Resolution is 1280 by 480 pixels, with 16.7 million color capability. Aspect ration is 8:3.

Cheers!

OUTSTANDING CARL !!! I ran across your post today and it's like a good book could not put it down! All your engineering improvements I totally agree with plus your workmanship. These changes are what the new 928 should have.

Thank you Tony,

You have an awesome looking project going on yourself. Very nice and professional looking.

Cheers!

SO, finally, I have the wiring information back for the replacement Bosch wiper motor. I am posting the diagram on how to wire it with the Infinitybox system below. It is very possible that it can be adapted for the stock 928 but I have not looked into that as it is beyond my project. Perhaps some of our electrical gurus can look at the posted diagram and then see if it is possible to adapt to a stock 928.

Using this motor will cause 2 things to happen. First, the motor has only two windings, which means out of the box it will only have low speed and high speed. I am losing the medium speed. For me that is acceptable as I don't think I have ever used all three speeds on the 928 before. No-go issue for some individuals but I can live with it until another better option appears.

Second, and this is due to an Infinitybox limitation, the interval wiping is no longer available, sort of. The system is unable to take a variable voltage from the stock rheostat and translate that into a "delayed wiper pulse". It is however perfectly possible to set a fixed delay, so I have the system programmed for a 3 second delay between wipes right now when in "interval mode".

So, the recommendation for those that want to keep all the original wiper options when using the Infinitybox system, is to retain the stock wiper/washing system completely stock. It is fairly easy to isolate that sub-system and remove it from the old stock 928 wiring harness.

It seems the biggest issue with any wiper motor like this, is to get it to PARK correctly. The stock system has no internal park function either but uses the interval wipe relay and (I am told) the wiper stalk innards as well to signal the park signal.

Wiring diagram below, and the wiper motor harness under construction before being sealed up. The two InvertMini boards are located inside the cloth wrapped section. The entire harness will be sealed in heat shrink before final install.

Small update, the 4-pin brake pedal switch is installed, and terminals labeled in the picture. As the switch body and thread is plastic, the use of metal retaining nuts is not recommended. I am using them temporarily while I source the correct nylon nuts.With extended use the metal threads will damage the plastic thread on the brake pedal switch.

Also installed the wiper motor and once it is tested, the harness will be sealed up properly.

In preparation for Al's 3 **** HVAC controller, I mounted the fan amplifier module in the fan housing to ensure proper cooling flow over the cooling fin. With a template made by Al and printed out locally, I cut the opening in the plastic housing. The amplifier itself has a sealing gasket ensuring a weather tight seal. Two stand-offs will be located inline with the mounting holes to ensure that the plastic housing does not bend or crack in that location.

As can be seen in the picture, there is plenty of clearance between the cooling fin and the fan blades. The amplifier is used on the 2005 Nissan Altima, and probably several other Nissan cars.

Also received some new (man. date 02/19/2016) upper door glass seals and some trim pieces that were needed to finalize the door glass install.

Cheers!

They had both left and right sided upper door channels? When we were at that point with Minerva one side was still listed as NLA. Good to know they exist again.

FLYVMO

Sure did, I guess they just produced a bunch this year. I think the production date on one was February and the other one was June of this year. Amazing how soft the new ones are compared to the originals.

(I'm trying to keep up post-726 above) Totally digging the way you integrated the brake light/cruise control switch-well done (as usual ) T

FLYVMO

Thanks Tony,

The part number for the brake pedal switch is: PRF-80176 from Summit Racing. It is made by Painless Performance.

The programmer is being sent out today for your system.

Cheers!

Ordered. Thank you Carl. T

And final picture of fan in place with amplifier module installed, stand-offs still to be added. There is more room between amplifier and firewall than the picture eludes to, so replacement of the amplifier should be possible without removing the fan.

Cheers!

Haven't seen Big Al posts in a while ... has the rotary **** controller moved forward or are you just doing the amplifier in anticipation?

FLYVMO

Hi Tom,

That project is ongoing and I just spoke with Allan two days ago. He is hard at work on it, and while I don't want to put more pressure on him, I believe I will have a field test unit in my hands in November. I am sure he will chime in with updates. He is very thorough and is spending a lot of time bench testing and fine-tuning the code and hardware.

Cheers!
Carl
