I hope somebody knows exactly why i'm having the following problems, it would save me a lot of time and brain cells, and it would be much appreciated.

RX7 S5 13BT

- Just rebuilt motor myself

-Just upgraded to LT8 from my MT8 that blew a injector driver. Looking at the wiring diagrams they are the same so didnt change looms and just plugged it straight in.

1) Could not load my old map from my MT8 handset into the LT8. The MT handset is compatible with the LT isnt it? so i put a base map for my car into the LT. Runs OK, a few misfires.

2) Get ERR for my RPM and REF.

3) Microtech handset displays i'm doing 1300rpm idle, dash and apexi displays 650rpm, engine sounds like its going somewhere inbetween like 1000-1100.

4) ERR on AT - Air temp display on hansets is always reading negative -11 to -18 regardless of which way i plug it in.

Theres probably a few more small things i cant remember, but the car is running OK, not as good as the MT8 with the same base map, after rebuild, just before the MT8 blew, it was running smoother. I think i need to readjust the timing CAS.

Thanks and Regards

You sure the harness is the same?
