MEMCAL 9930 Wanted.

Postby Neil.G » Wed 06.10.2021, 14:50

Afternoon all,
MOT due and the end of the month and I'm in need of a 9930 chip to help with emissions, I can do an exchange with SJS but believe they're on back order with Lotus and didn't really want the car off the road in the interim. Has anyone got a spare hidden away in a box they want to sell? Or trade? I have a spare sump in pretty good condition or a cam cover that could be polished up a bit.
Cheers all.

I have got one...... somewhere......

...... I'll try and remember to have a search through my spares in the garage.... or the loft..... or the little bedroom......

....It'll be in one of those 3 places (hopefully)

{I had it in mine when I got the car but went closed loop, and I don't remember giving it to anyone.}

Just the one now, but this one's mine! - and it will be finished eventually.....

That would be fantastic Dave,
You must have a tonne of spares to take up so much room. You appear to be custodial gatekeeper of all things elan, I have one of your old engines in mine.
Thanks,
Neil.

Neil,

I have searched through my 'usual hiding places' but failed to locate it, sorry.

I did find a 'mountain' switcher chip which has the 9929 & 9930 profiles on it (according to the writing on it), but not the original 9930 chip.

All I can think is that I have donated it to someone in the past, as I wouldn't have thrown it away. Sorry again. :(

Morning,
I appreciate you searching. Never mind, looks as though the SJS route is the only way forward, best get my order in pronto.
Again, thank-you for trying.

Afternoon,
My 9930 MEMCAL is on its way. Any advice on set up? I'm happy with fitting to ECU but is it a case of setting O2 potentiometer back to nominal and resetting ecu? Is it a case of counting turns of CO2 screw all the way in and then halfway back? Is the only way to use a multimetre off the car to find active window of potentiometer and screw it out to lowest setting?
Lots of questions, hopefully not all daft.
Cheers,
Neil.

Hope you've got your emissions under control now Neil!

BTW If anyone has an Elanscan download of a 9930 prom they could send me it would be great.
I'd like to investigate what changed between 9929 and 9930, and also have an idea for a small project...

Hi Ron,
Yes, new Mem-Cal made a huge difference. My previous Co2 readings were at 5-6% an obvious MOT fail with the upper Elan SE allowance set at 3.5%. Using a multimetre I set the new chip to 401 ohms and the car sailed through emissions at 2.9% :clap: . As previous posts have indicated the window of chip operation is very small and a minute turn of the screw makes a huge difference. Anyone in the same predicament should take the time to remove potentiometre and manually set it using multimetre, although spark-plugs and leads will of course play their part. Mine were changed the year before and I also used 99 ron fuel to cover all bases :D
Cheers,
Neil.
