Can't wait to see how your motor moves the truck!

What I did today,   :dD>:

Got the driveshaft in.

Ordered a 1238-7601 controller, No OS or VCL.

Gone a put my motor back on the dyno with the new controller and get it all set up,
then I will put my motor in the truck.

I put my 10HP motor back on the dyno just to run a new optimize (did not have the current maxed out last time) I will re-optimize when I get my new controller.

Here is some numbers...

RPM right at 5000

Slip Gain   Motor was optimized at 7.5  did a locked rotor test and here is the numbers.

Got new numbers down a few post, with new controller 1238-7601
http://ivanbennett.com/forum/index.php?topic=17.msg1482#msg1482

lower numbers on slip and torque started going down.

So the best is 3.5 on the slip gain, gives me 230 foot lbs of locked rotor torque. :>ba:

I am happy with that...........

230 Ft/Lbs....Impressive. Considering my big 20 HP motor did not do a lot better than that.

The ability to change and set all of the parameters and have them stay that way is absolutely necessary when you do your own motor.

Even on my AC50, I wish I had been able to do that.

What exactly does "NO VCL or OS" mean? I mean, I know what its talking about, no vcl or os, the control software. Do you have to load or flash your own vcl/os to the controller? Is it an electronic "brick" until you do? Or is it a functional controller as received? Or does it mean it hasn't been set up for a specific motor, and you have to optimize it?

I found out awhile back that Curtis has there own VCL and Operating system in every controller,
or it would be just a brick.

So don't need HPEVS vcl or there motor parameters.

The Curtis OS and VCL lets you do everything (change).  But I do have software, just in case.

In computer speak.....

Every Curtis controller has a Built-in-operating-system. (BIOS)
                   It is burned in the mother board.  Basically everything you see in the HPEV firm ware plus a LOT more...to
                   suit every possible use the controller might have. (Airport tug, mine rail car, hydraulic pump for a remote machine...ETC)

Then when the controller is wholesaled to a manufacturer, THEY over lay "Their" VCL (Vehicle control language), it masks some un needed
                      Items in the Curtis Bios.  It also sets some new limits to some parameters.  All set by the manufacturer and to suit their products.

We (Ivan and I) have a motor type not envisioned by HPEV. Their VCL no longer works well for our motor's needs.  We need our own VCL overlay. 
                      It blocks out the "hydraulic pump", and other things we do not need.  BUT it opens up others we DO need, such as an adjustable slip gain parameter.
                       (And other things.)

Ivan's controller will have the original Curtis BIOS.  (Everything is wide open.)
My controller has the same Curtis BIOS, PLUS a VCL overlay allowing Torque mode only, adjustable everything and the un needed "hydraulic" drive stuff masked out.
                    (A custom "Basic" VCL)

What I did today..   :dD>:

Got the transmission pump mounted and plumbed,  ready to put some tranny fluid in.
Run 3/8 soft copper for the suction line and 1/4 inch steel braided line up to the trans port,
with a check valve.

This pump has 60 lbs cut off on the switch, my tranny guy said 60 psi would be enough to hold
the clutch plates.

 :Dr>:  Got the new controller 1238-7601 and mounted on the dyno, went through the setting
           and got most of my setting programmed in, it is to f-ing hot out in the garage today 114 F.

 Will optimize the controller and motor tomorrow.

 :sf<:   This is where the controller will mount in the front of my truck fire wall.

         That is the cool plate, water cooling for the controller.

        I had it siliconed on to the other controller 1238-6501 what a pain in the ass to get that off.
   
      probably should of listened to Miz on the anarobic gasket sealer.  oh well.

 :Dr>:  Did the optimize with my 10HP motor and my new 1238-7601 controller.

Here is the numbers after the locked rotor test.  The motor optimized at 7.00 on slip.

slip       torque      amps
7.00       142       260
6.00       160       270
5.00       180       280
4.00       220       270
3.50       225       254 

  Looks like 3.50 is the best on slip gain. Had to turn brake pressure up all  the way to hold it.

  All so seen over 5600 RPM and no field weakening.        Can't believe it.

The top meter is the scale foot lbs.  meter down below is amps from batts.

Can't wait to see the rpm and torque numbers when you get the field weakening set and graph it all!
