Hi Hondata Guru/s
I am building a car at the moment which is a bit of a mongrel. It is using mx5 nb (miata) gearbox, brakes and uprights mated with a K24a2 engine (k24 here in AUS). The ecu I'm using is a 37820-RBB-A71 (auto) and using Flashpro with a manual tune entered into the ecu. I'm not running any other honda stuff from the original Acura TSX such as ABS, VSS or Dash instrument cluster.
I am enjoying the Flashpro functionality but need help with a couple of things.
1. What is the pulse per mile output of the high frequency output VSS sensor of a TSX?
My mx5 sensor is of a variable reluctance (2 wire type) so I am using a converter to get 5 v square wave output signal which I have then connected into the RBB-A71 ecu at Input A18. But it seems that this is only giving around 4000 pulses per mile as most sensors do. What is the usual PPM for a high frequency honda VSS?
2. Since I'm running a custom dash cluster with aftermarket gauges, I have no ability to see a MIL light indicator on my custom dash as the ECU I chose doesn't have an MIL light output (only RSX Ecu's it looks like). The TSX shows the mil light by using the OBD2 communication between a regular dash cluster and ECU from a TSX.
Would it be possible to update the flashpro software to have an unused output from my chosen ECU to be converted into MIL light functionality ie maybe a switched ground ecu output to give indication?
Looking forward to your replies. Keep up with the excellent work that is Hondata.

Re: Flashpro in custom Locost car (think Lotus/ Low cost)
IT is probably over 100000 pulses per revolution, you will have to try different values. You would have to count the number of teeth on the 3rd gear and calculate based on the final gear and tire size.
There is no way to add another output for the MIL.

Hi Spunkster
Thanks for your reply. Regarding the MIL, is there something that I could use that would pick up the MIL signal from the can bus lines. Surely it could be programmed to another ecu output?
