Okay, here's what is going on with my PS2K, Serial# is 514001009943. No CAN devices are being used, everything is strictly through the two main connectors.

I want to use AVI #3 for a generic idle-up function. My harness currently has it do a relay triggered by the A/C compressor gives 5v to AVI#3 whenever the A/C is on. In the manual, it states that one can use a DPO and AVI together to accomplish this, but having the ECU cut power to the A/C isn't necessary or desired in my build. Pretty sure if there was a need for killing the A/C in a FC at high engine RPMs, Mazda would have implemented it in the stock ECUs.

After a few emails to Eric at Haltech about this, he recommended upgrading from v1.07 to v1.11 of the ECU Manager. Did that yesterday and upon initial connection to the ECU, it upgraded the firmware to 1.06.2, but did not list the Generic Idle-Up option in any of the input drop-downs. I do not know what firmware was on the ECU before this, but it is 1.06.2 now.

Figuring it was just some random quirk, I hooked everything back up again today and received the same "upgrading to 1.06.2" message upon initial connection. After it disconnected (loose pin in a connector), a message popped up in the Devices pane of the main window, stating that I need to upgrade to 1.09.2 to take advantage of additional devices such as the I/O Expander 12. Upon reconnecting, the message disappeared. I have managed to make the message reappear by disconnecting in the File Menu.

On Haltech's site here (Haltech – Engine Management Systems » ECU Software & Firmware), the newest version of ECU Firmware is listed as 1.06.2, not 1.09 as the Devices pane is asking for, nor do I see any option or download link for 1.09.

Is there something I am missing with this? The Help File is pretty much worthless in regard to firmware updates, and makes no mention of the Generic Idle-Up function I wish to implement.

thanks,
AWC

EDIT: Updated the firmware through the menu to v1.09.2 and the Generic Idle-up function appeared as an option for th AVIs, but lacks any form of settings such as an Offset when active. Also, the Rev Limiter activation RPM is gone now. Used to be in Main Setup>Advanced>Rev Limiter tab, but is not there or anywhere that I can discern.

 

I have firmware 1.09.

go to Tools and try the "Upgrade Firmware Version".

Should dl and upgrade it automatically.

I see a "generic" idle up request but why don't you use the "A/C Request" function.

 

I don't need or want the ECU trying to think for me when I'm perfectly capable of knowing to turn the A/C off at 9000rpm. Maximum operating RPM for A/C Compressors is documented and available from the manufacturer (in this case, Sanden), and a suitable RPM cutoff point can be calculated by this and the pulley ratio between the compressor and crank pulleys.

If this were going in someone else's car, then having the ECU think for them in regard to the A/C might be a good thing.

I've finally figured out the new & improved rev limiter. Instead of the simple way of "put in a number and it keeps it there 24/7/365" in the Setup Menu, it is now an on-screen Text View Gauge, calibrated against the Coolant Temperature Sensor. This allows one to have a rev limiter that is dynamic with the engine's actual temperature.

Again, not necessary for one whom uses their brain and knows the first rule of rotaries: Don't Flog when cold!

As these change are not documented in the release notes or manual AFAIK, this really gets a negative mark on Haltech based on the criticality of the rev limiter to basic operation, not to mention how there is essentially zero information regarding using the Generic Idle-Up capability.

 

The rev limit table is referenced in the manual....... I'm not sure when it changed as that is how I have always seen it.


"Soft Cut Range-

The RPM Cut Range value sets the RPM at which the first cylinder will be cut. The Rev Limiter will progressivley cut more cylinders as the Engine RPM increases beyond this point.
All cylinders will be cut when the Engine RPM reaches the value set in the Rev Limit Table in the ECU Navigator. "

 

Sesshomaru, you are correct in that the Rev Limiter was documented in the changelog, just poorly Anyway, ECU is set up for soft rev limiter to start at 8000, end at 8250

As for Idle-up information, it is hidden in the DPI section of the Help File, which lacks any form of a search capability. Whoever wrote the manual really needs to get a clue because it's worthless if you can't find information on inputs/outputs and so on.

Currently sourcing a 20B BAC Valve to address idle-up requirements. Kind of annoying that I have to use the last DPO, but stuff like this is the reason why I made the Haltech harness modular with everything on subharnesses.

Even with every input & output used, Haltech says that it will do just fine through 15000rpm

 

I don't know about you but I changed my tables to suit what I'll realistically be running.

For me 15k is a bit high and I just maped it 1k past my rev limiter (9k) so that I get better resolution.

I am using the full 32x32 map - this is one of the main reasons I wanted the ps2k.

I have noticed none of the maps posted on this forum are 32x32.
