Yes I'm running one of RonR's dual chips in my 9239 SE, added the extra wires, an O2 sensor and went full 1499. Best mod ever imo :D.
And yes, you're not alone in falling foul of those 'dinosaur' rear brakes. Jamie does a Honda type-R rear caliper upgrade - and the prospect of handbrake fail is now no longer an issue either...
Always good to get feedback too. :D

I'll PM you with more info & details.

CAS: In the M100's distributor-less ignition system the Cam Angle Sensor (CAS) sits on the end of the exhaust cam and sends signals to the ECU as the cam rotates. The ECU then decides when to fire the coils and how much fuel to inject. The timing's set by putting the ECU into service mode and rotating the CAS until the engine fires at 16 degrees BTDC.

BTW You don't need to set the CO Pot if you're Closed Loop, S2s don't even have one fitted.


Hi RonR.
please PM me as well for the information you need from me, so i can purchase the correct chip for my 1991 Elan. looking forward hearing from you, Br. Lars

MOT update, fitted new rear brake pads, adjusted calipers and cables
Passed with 20% efficiency so all good for the summer.
Ordered the Honda kit from Jamie so will fit before the next MOT
Thanks to all for help and feedback

Hi Ron,

I have several M100 customers who are looking to convert to the later chip and O2 sensor format. Would you be able to supply me with a couple chips?

Kind regards

Hi, I'm pretty new here. My BRG Elan has failed its MOT on CO2. I'm very keen to get hold of an Everest chip as I try to get it back on the road. To misquote a certain fictional princess 'help me RonR, you're my only hope'

Regards
James

Hi James,

Assuming your car's an SE, not an S2:

Sometimes MOT stations wrongly test emissions for SEs according to the data for S2s which are much stricter as they were fitted with catalytic converters, so please make sure the test was carried out with reference to the Pre-August 1992 specs.

First thing to try is the CO Pot adjustment procedure: https://wikilec.com/view/CO_adjustment It will need to be adjusted with an exhaust gas analyser.

If the pot's at minimum and the CO's still too high, maybe a 9930 prom would help. It adjusts the range of the CO Pot at idle so that lower emissions can be dialled in.

An Everest chip in itself won't help with CO readings, a 'closed loop' conversion will. It lowers CO by adding an O2 sensor which tells the ECU how to adjust the fuelling for minimum emissions. The details are in the Wiki here: https://wikilec.com/view/Converting_SE_ ... d_loop_ECU

I can provide the 9930 or 1499 chip for the closed loop conversion with standard boost profile or with the Kilimanjaro or Everest increased boost profiles.
