It's an fc3s with haltech 1500 and pre terminated harness for fc and direct fire coil harness.

Problem is I'm not getting any crank signal. No rpm no fuel no spark. I uploaded the provided map for direct fire.
Any ideas.

 

I just finished installing my 550 this weekend and found out I used the wrong 12V switched source, so the ECU was turning off during cranking. I just moved to another source and all is well.

By "not getting any crank signal," you mean the starter engages but all the engine does is turn, correct? If so, is your ECU staying on while cranking?

 

While the haltech "base" maps are a pretty decent starting point, they very rarely are completely drag and drop as most RX7s have been modified outside of the general stock form of the car for which the basemap was designed. Most setups requiring minor tweaking to suit the specific setup of the car, you're gonna want to check the IO in the file you are using against the wiring of your harness first off.

Yeah, need to know this first. No point in chasing signals and lack of fuel/spark until you know the ECU is getting power and starter is at least turning over the engine. I'd then check the I/O between the harness and software next.

I have installed and wired an e6x on this very car many years ago and I did encounter an switched 12v that cut while cranking. Currently that's not the issue. I did load another map and I got it to read rpm and get signal. So there was something off in the settings of the first map.

I managed to get the timing sync/set. But had to do whole cranking. the car will not run long enough.

I am getting error p0373
Looks like I need to find fc3s CAS voltage thresold.

 

The base maps have the thresholds for cranking speeds set too high. Lower them down and you should be golden. Also make sure the ground reference is set correctly in the trigger setup. It should be set to disabled for the Haltech flying lead and full replacement looms and set to enabled for the patch looms.

 

Thanks for the replies guys.
How often does rx7 CAS go bad... I've had them last me forever but I'm starting to question this CAS.
I was getting high rpm break up in my e6x which I suspected the OEM coils. But now...

C.ludwig. I got it to read rpm. original map that came with my ecu wasn't reading rpm. So Installed a base map from haltech which was for the elite1000. Firmware 224. this map read rpm. And seemed better. But had lots of trigger count issues and 4 home errors. I then found out i had to lower the arming and home trigger voltage. so I loaded the original non rpm reading map. And lowered the voltages bit by bit till it read rpms and it cranked. But just like the original map it had plenty of error counts and home errors. although it showed in diagnostic page "running" and lever "full".
Currently she starts up nice and quick and idle rough ish for about 10 seconds and stalls like someone killed the switch. if I hold it in higher rpm she smooths out for a bit and then stalls again. Sometimes I can pump the throttle a bit and before she reaches low rpms shes comes back and I can hold her running for another 10 seconds before she tries to stall again.


Also to satisfy my paranoia. how hot do relays get. They are pretty hot. I'm sure a child couldnt keep his fingers on it. Pretty hot... eh?

 

Have you had any luck so far with getting this running?

Also, I wouldn't expect relays to get toasty on a normal basis. In my experience they only get a little warm. You are talking about the relays in the Haltech box, right? I'll have a look at mine when I get the chance.

My relays get hot while trying to crank it. Haven’t felt them when it’s running.
Have you solved this issue? I’m curious to know to know what fixed it.
