Re: she's got no juice man
Sounds like your vaf aaron, if you have a 2.5 ecu you should deffinately be using a 2.5 vaf. I was told it's a must have for the swap.<BR>Try PARKWAY <A HREF="http://www.parkwayautorecyclers.com" TARGET=_blank>www.parkwayautorecyclers.com</A> or 1-800-265-6464, they're in Kitchener, I got my vaf there for $75.<BR>I still have my still have my 1.8L ecu, due to my auto trans, maybe I'll try using my 1.8L vaf and see how that works? If it does work, and well, maybe I"ll sell you my N.A 2.5L vaf for $50. [img]shrug.gif"%20border="0[/img]

Re: she's got no juice man
I solved the problem . I beleive it was a dirty connector because I removed the Tps and the vaf - tested them and put them back inh and now it's been fine for 3 days.<P>It would make sense because it would happen in the heat of the day ... maybe <P>I still would like to know what the vaf volume sensor is supposed to read , just to know if mine is shot. cause the values don't make sense <P>I also run the 2.5 vaf. the 1.8 makes the car so rich it looks like a diesel jetta<P>Talk to Brandan at Performance Improvement Guelph because I would like to test the vaf and possibly buy it if mine is shot<BR>thanks

Re: she's got no juice man
hey Brandon has a kl46? J-spec ecu for I beilive an auto I tried it in mine and all the power was down at 4-6k <P>but for sure the 2.5 vaf is the better<P>I'm thinking of putting a reostat in the vaf<BR>volume circuit to see what it will do for every day drivability I will post separitly
