Post subject:  Airflow meter.....CODE 8
Right, so i've finally managed to get some info out of the ECU with the diagnostic kit i got from MX5.co.uk, turns out i have to have the car running to get codes!!!

Anyway, i'm getting a code 8, which means possible open or shorted airflow meter, so whilst i go and retest to confirm the fault, i thought i'd get a bit of confirmation from the assembled masses....

....the airflow meter is the one that sits immediatly behind the airbox (if you've still got one) right?????

Incidentally, big cheers to Stu for sending me the link :D:D

yup theat the fella :D

see when u shorten or lengthen the length of the pipe between ur AFM/air box/filter and intake, u change the characteristics of the engine performance :D

Its always best to keep the orig length, mark T knows more about it I think :D:D

Right, the Mitchell repair disk, mentions a PCME that the AFM is connected to, what the f*** is a PCME, i have a suspision its something to do with the ECU!!!! :S

Wish somebody had told me that before I started trying to put in cold air feed :roll:
Still not sorted out the idle/tickover

Not quite true - it's the length of the plenum runners ... sort of .. :? Quite complex :?

I think the CAI will be OK.

Andy, what are you trying to do mate?

Mark, was it when we were talking to that bloke with his X WRX cossie in weymouth? was he talking about this? was i just not paying attention as usual? I thought he said if you make the length of the intake to filter longer u make the car have ligher end power? and if u shorten it it makes lower end power?

It was a turbo, so he wouldn't have been talking about that. This is really an issue for normally aspirated (NA) engines.

According to my 'sources', a longer plenum gives better low end torque, which is what manufacturers tend to design almost all cars for these days :D:D

Yep, that sounds right and confirms what I said above. It's the individual intake runner lengths, not the whole intake length that affects the pulse tuning. The intake length will affect the resistance presented to the air going to the engine though.

Yup :D:D

Just got me a second hand AFM with intake pipe and airbox (for experimentation;) ) for £30, chuffin good price if you check out how much it costs on the EPC :D:D:D

FINALLY scored a broken front bumper too, also for experiments, for a fiver, RESULT :cheers:

Did you happen to come across any fog lights on your scrappy travels?

Also, that's very cheap stuff :)

Post subject: 
No, sorry Adam, only ever seen one F with fogs in a scrappy, and one of those was broken :D:D

Tip on scrappies..... if you go to yards that don't specialise in a particular make, they tend to be WAY cheaper than specialists :D:D
