ELANSCAN DATA SET

[Chas54]

Has anyone got a dataset from a 9930 chip car. Precat model or can anyone point to one already posted?
I was hoping to compare mine with another set to see if I could spot anything amiss.
I changed the 9929 memcal due to being unable to achieve the MOT required CO levels.
Mine are now at 0.5% but I have a minor problem with the engine slowing when pulling up at junctions. Feels like it might stall.
I also have an issue with the IAC position not returning to count 20 when the car is idling after the fan cuts in then out. The engine speed drops off a little as the fans start, alternator load increase I think.
At that point IAC count increases and once the fans stop the IAC decreases to 21 ?

The ignition advance wanders a bit erratically at the point of fan cut in and out , and I wanted to compare this with someone else's good data set.

just at the moment I have lost the ability to Zip file anything on my PC---- result of computer upgrade and windows 10.
I can still unzip though.

Charlie,

I have had a look through my old elanscan files, and this one shows it was a 9930 chip....... but as it is named 'mountain route' I asume it would have been Angies red Elan from when we went to the Isle Of Man.....

..... as such, it won't have been a 'standard' chip as I had a switcher chip in that car, so the map may have been set to anything!

(most of the other elanscan results I have for a 'standard' chip are for 9929 or 1499 eproms).

This is a scan with a 9929 chip which may or may not help, but the car was running brilliantly!

Here is a data set from my Elan a few years ago. Again, it's a 9929 with Everest mountain chip.

Hope it helps.

Thanks

I will have a look at these and see how they compare to mine, although the most recent I have was stationary from cold watching the fan cut ins and seeing there effect on the IAC position.

I have this one which is a static run up to temperature, but with a couple of throttle 'blips'........

Dave . Thanks.
I have compared my idle data sets and noticed that the voltage drop I was concerned about may be absolutely normal. But the idling speed of your car is higher than mine at 1025revs, I had been setting the idle to 950 . Also on yours the IAC sits at 2 counts whereas my understanding was 20 counts at idle would be the norm. Looking at some of the other data sets that I could find posted from people, I may be trying to achieve something that isn't that important , I cant find a set that has the IAC at 20 on idle. I may be looking at the wrong sets as its mainly people with a problem posting them.

I noticed your chip was 9929 but I think you said it wasn't a standard set up .

I have been out today for a drive round to relearn the IAC position - ive fitted a battery isolator so had to do this. On return and idling in my driveway I could see the IAC at 15 counts until the cooling fan cut in at which point it moves to 19 -- I guess it see the dip in revs as the alternator loads up, on fan cut out the IAC goes to 17 . I thought it should have returned to the count 15 ?

Now the CO reads 2.5 %

Thanks for your comments though, and indeed if anyone else spots something i'm doing wrong please let me know

Ive posted my 2 runs done today for anyone to comment on .
1st is the learning run for the IAC
2nd is the return journey and idle up to fan cut in on driveway
