Electronically upping a 1.9xu idle by 500 rpm

Recommended Posts

Thanks for the input Forbes..... that sounds like what the guys on here have suggested?....

 

but intead of a manual tap, using an electronic air solenoid so we can use 12v instead of turning a tap..... 

 

your theory is spot on tho..... :)

So far I’ve fitted the two T pieces into the pipe just behind the afm and the pipe leading to under the inlet manifold?.... they are what I think are in parallel with the sad valve.... 

 

ive capped them both off for now.....

 

but the car now wont idle when cold lol!!!... I don’t know if my tee pieces have caused a reduction of air flow to the sad valve? Or if something else silly is being overlooked lol....

 

im going to have a look again later, but for now I’ll draw a pic to show people what I mean :)

I’m not sure if them 2 tees restrict air flow that would normally flow through the SAD?? 

 

They are 16mm O.D and 13mm I.D so knock the internal size of the pipe down by 3mm.... 

 

either that or ive knocked something when putting them in and caused a problem.

 

i am going to get the car running correctly again before installing the valve.

I’ve just finished installing this air solenoid in, and it definitely works to raise the rpm. 

 

It went from 800rpm with the valve closed and to 2000rpm with the valve opened (energised)...... so now just to fit an air screw to fine tune the rpm and I should be away!!!

 

thanks for all your help and advice !! :)

Finished now.

 

thanks for everyone’s help!... the car now idles around 1000 rpm with or without the air con on :)

 

the air gap needed in the link was about 5mm..... 

 

The 5mm gap seemed to up the rpm from 1000rpm to 2000rpm in test without the compressor calling for demand, so I thought that would be too much??.... but with the compressor on it seemed to wipe that 2000 rpm down to the 1000 rpm I was looking for..... 

 

now just to find a few places to go! :)
