heres how it goes from the start,i decided to upgrade my WR1 just before xmas so that i could do the work over the holiday period..so i got the parts ready bigger turbo,750 injectors,decat downpipe,stainless manifold and wing mounted air filter to go with my APS top mount,3" exhaust and NGK PFR7b plugs i had..
Now i took off all the old parts which was a mission,but i managed it and started putting all the new parts on which again i managed just.after i had put it all back together i knew it wouldnt run like before but thought it would run a bit better than it is.

Now for the problem,on the code reader it is saying clyinder 2,3,4 and its running lumpy.i have read allsorts on here on what it could be and have noticed Neutrol postion switch could be a problem,but the car was ok before i started.

any advice would be welcome before give up on it

Thats ALOT of upgrades! Did you not think of getting it remapped just after fitting them? Your ecu wont know what the hell hit it!

Gav, did you re-map it after to cope with the bigger injectors?

I assume you probably did but just ruling it out.

LOL you have fitted bigger injectors, the ECU doesn't know that.

Once it's mapped all will be fine I'm sure.

The neutral position switch can fail and you wont notice much of a difference other than being a litle hesitant due to the fact the variable valve timing drops and comes back up again as the switch glitches..

But ignore that for now, you have a load of parts fitted which the ECU cannot cope with in standard form. GET IT MAPPED.
It will absolutely without doubt run like a bag-o-****e until you do.

Assuming it hasnt been mapped. I wouldnt drive it until it has been.

when i fitted 650cc injectors in mine before the map it ran very rough ie cutting out when coming to a junction,the ecu struggles to cope with the 650cc never mind 750cc plus the othe stuff u have added,amazed its running at all lol

it hasnt been re-mapped yet i have been intouch with simon (JGM) to solve that issue..just thought i would be able to get it out of the garage and let it tick over..so would the re-map iron out them problems?

50 % bigger injectors, no way the ecu can adjust for that !

My neutral switch just meant the AVCS didn't work so the power delivery was very smooth, but no kick as it should have as the ACVS trgged.

HTH

Most definately. You have made some MAJOR changes.

Please dont drive it to the remap.

Fuzz

Bah it's not that bad unless you have to drive half way across the country.

I drove 30 mins from Cheltenham to Swindon with 750's in.

Just drive steady and it'll be fine all be it pig rich
