hi guys im doing this to my 99classic as they are fragile buggers so i will have the maf sensor soon but what else do i actually need. can anybody post links to what other items an does anybody know how they wire up.
thanks for your help

You'l need it mapped again, might be an idea to let the mapper splice the old MAF wiring and fit new MAF

it will be getting remapped next month but wondering if i need the newage pipe for it to fit or can it be fitted to the original pipework

dont think it will fit into the classic housing with out some sort of adapter

seddomyster

yea ive looked between the old and new an are different but if it did then main thing is not to leak. an dont know if newage maf pipe fits the classic

No one local to you with a newage, so you could try the maf housing for size?

nope dont know anybody wit a newage car. ive got the maf sensor coming in next few days an has been done in past as people said. got a month to do this

The MAF housings are completely different, The Newage has a temp sensor incorporated into the casette as well. If this was easy and doable then it would be written up on SN.

i will ask my mapper an see what he says. i wrote a thread other week an bob rawle said its be done but dont know what i really need

I've got 2 different types of maf housing as well if you want?The OEM one and one thats left over from the HDI FMIC kit i bought

seddomyster

iTrader: (9)

can u post pics mate. may buy 1 but dont know if they are bigger or smaller diameter pipes

Will do bud,but it will have to be tomorrow.Their both in the shed.
I'm sure you'll be able to buy a reducer for them.

yep mate thanks. i will buy 1 of them from you an then see from there. cheers mate

I know that Bob Rawle has wired up and mapped a Classic with a New Age MAF sensor and body fitted. I think this was on a 99-00 and one MAF has three wires and the other four from memory so it is clearly possible and as Bob has done this already he would be the man to repeat this for you.

Bob Rawle

I have done this. You cannot use the original MY99-00 maf housing, the maf output will be insufficient at light throttle and idle. Given the correct maf tube diameter then the maf scaling needs a significant revision, however given that then it works v well and the car will drive the same if not better than if the original was in use. The wiring needs adjusting to suit of course.

best regards

my99 car has 4 wires upto the maf. from what ive seen the newage uses 5 so im assuming the 5th wire is the AIT sensor. is this the only wire to wire up or are they routed differently. i will soon have the newage maf an a pipe to suit but what is the scaling?

harvey

iTrader: (48)

Scaling the MAF sensor as you now have a MAF sensor sending information to your ECU from a different diameter tube so this needs to be scaled so the correct fuel is added for the air flow detected by the MAF Sensor.

seddomyster

iTrader: (9)

cheers for the info so basically scaling is to do with the remap? once the snsor is connected an all together the car wont be run but would the car still run if its conected wrong? just so i know if its wired up correctly or not

iTrader: (2)

Scaling is required because of the change in diameter of the MAF housing, all the MAF does is measure airflow. stick the MAF in a 1" diameter tube with say an airflow of 10cm per second and it will tell the ECU a certain value. Stick the MAF in a 12" diameter tube wth the same airflow of 10cm per second and the MAF will tel the ECU exactly the same value...........because the airflow is the same.

Even if in the second case the airflow in the pipe has massivly increased because of the change in diameter.

If you increase the diameter of the MAF housing the result will be underfuelling and running lean. The ECU should be able to cope open loop

It really needs fitting and mapping pertty much together AFAIK.

Shaun

PS Had the RCMS Induction kit fitted and Bob Rawle had to rescale the MAF and (as ever) Bob told me what was going on. I hope for Bob's sake I heve remembered right

took pictures of my maf sensor. original is on right of pic an newage on left. original has wires from left
1. green an black
2. light green
3. black green
4. yellow green
from looking at colours it seems 2 are straight swap but what about the other 3 on the newage maf. hope some1 can get back to me. thanks for looking

actually. how do u post pics

seddomyster

iTrader: (9)

cheers for info mate ivejust realised u wrote as i just went straight to reply. ive got the pipe now an just need to re wire. anybody know what colours go the what

If you look in FAQ you will see how to post pictures.
Sorry can't help you regards the wiring to the MAF

cheers harvey. had to add in my album
https://www.scoobynet.com/album.php?albumid=4044
which wires connect to which if anybody knows.
newage left plug an car loom right plug
will be cutting off old maf plug and attaching newage
