OK great but fine if dealer is setting up.

As per title really, does the PRA euro ECU and K100 support the TC module?

Started first time and idles super smooth, just need to clean up the wiring and put undertray back on for a test drive. http://farm6.static.flickr.com/5210/5234632757_2f58a268f9_z.jpg Oh and I have OBD2 bluetooth to android to check on faults and parameters! https://p.twimg.com/AiaUFntCQAEODij.jpg

Yellow is multiplex but on the E8 plug, the C101 is all the chassis to engine connections.

Ok from reading a tracing the loom, C101/17 looks to be ECT feed for the dash (it loops off the C101 up to the E, hence two cables)

Pin 2 Yellow, is the 12v feed for the back up switch.

(long day!)

C101 is on the dash loom with the E plug, and hooks into the engine loom along side the A&B plug.

Also wondering what pin 2 (yellow) does too!

Hi

The lotus O2 relay is hardwired to the main relay (in one unit) so it just comes on with the main relay.

Question is, does E8 need to see a 12v signal to not think there is an issue with a dead relay?

Hi

Have searched, read docs, looked in Hondata FAQ and still can't figure out what pin 17 does on the C101.

It has two red/wht cables on the one pin, and FYI this is a UK spec (PRA) loom and ECU.

Any help much appreciated.

Ok so I'm clear now, it was as I thought. It's the relay coil gnd, which means 12v will be going to it when the main relay is on but it's not being fed constant 12v.

Hi Just building a swap loom up and I'm a little bamboozled by some of the info around the PGM-FI relay, I'm sure it's simple just want to be sure as the following warning is scary enough: Do not wire the main relay (E7) or fuel pump (E1) to 12V. This will damage the ECU. Both E1 and E7 are outputs ...

AH fair enough

Ah shame, is that a limitation of the PRA ecu?

Would have thought the majority of swapped cars aren't fed elises as I am not aware of kits for them?

Hi

Noticed in a later version of the software there is support for driving Lotus clocks via the multiplexer out. Any more info on this?

My car is a UK lotus elise, with a PRA ecu and loom. Swapping to later clocks with the higher rev counter and 3 shift lights could be a nice upgrade.

Hi It looks like I need to use a PRB ecu in order to drive an AIM dash over RS232, so have been reading up on the differences. I know I need to buy the PRB wideband sensor and some wiring changes as outlined in http://www.hondata.com/techk20-ctr-o2wiring.html However is that the limit of the changes...

many thanks

Hi

With the K100 application, does it matter which numbers are on the end of the ECU code?
