Throttle bodies

Post by Allan Brown » Thu Jan 20, 2011 8:54 pm

I am thinking of putting Jenvey or similar throttle bodies on my Seat Arosa.
Has anyone had experience of fitting throttle bodies to modern ECU controlled cars?
Would I be able to use all the standard sensors or would I need different sensors?
Could I use the standard ECU and get it re mapped or would I need a different aftermarket ECU if so any recommendations?
Can anyone recommend a good rolling road to do ECU re maps?

Thanks
Allan

Hi mate done a couple of conversions but all the ones i have done have been stand alone system running new ecu , I believe yours doesent run a AFM and uses a map sensor system so i would think you will be able to use the old ecu and sensors on the manifold . The problems i have had is getting the throttle bodys to work with the lambda sensor as they always seem to want to slightly over fuel at idle . I will speak to my specialist tomorrow and see what he says about the fitting and setting up , Btw i have always found the webcon tbs to be the better system and they have a good aftersales system which is only just around the corner of my workshops . Good luck :D

Allan, you could talk to Dave Walker, up at Emerald. Their K3 unit is a very good ECU, plus he has his own rolling road :D

Andrew at Bradley's Garage (Shipton under Wychwood) is good in just north of Burford (oxfordshire) - he is very helpful - had my imp and clan in throttle bodies and run on emerald setup there

i used 36mm keihin TB from a honda bike - better sized for a smaller engine and more compact

should be able to reuse most of the sensors as long as the ecu you are going to use allows youto define the resistance curve and outputs for each..


question? if it worth the hassle though? better doing suspension stuff

The suspension is already pretty well sorted on my Arosa and it handles really well.
The problem I have got is my car is about 900kg and 100bhp, When I am competing against 1380cc minis producing similar power and only weighing about 650kg I either need more power or less weight. As I run in road going I can't remove any interior to save weight so I need more power or a mini.

Do you still have the other "mini" that has been sat on?

Yes I still have the Mini Marcos.
But it needs a new gearbox.
I got the Arosa so I could do Solo's as well as sprints.
