I did a JDM S5 swap on my 87 TII. I have the JDM S% engine harness and USDM S5 rear interior and lights harness. I had a problem the car was cutting fuel when it went to boost. I was unable to get my S4 guages to work. So I hooked up the Apex AVC-r I had baught to use as a tak. The AVC-r worked great gave me good reading on RPM's, injector duty, and TPS. In my atempt to fix the cutting fuel problem I noticed the tps was only reading 28% on the AVC-r at WOT. So I made some ajustments ( moved the TPS back and bent the metal peice that the upper part of the TPS rests on) in order to get the reading on the AVC-r to be 100%. I than unpluged the temp sensor that was just sitting in the front bumper ( new S4 radator S5 temp sensor doesnt fit in it and the wires for S4 temp sensor broke off the temp sensor ar the sensor so no hope of reataching them to the S5 sensors wires) So I am rnning with no rad temp sensor now. I take the car out for yet another drive. I warm up the car slowly bring up the RPMS in 1st (in order not to boost) to 7500 per AVC-r readings. No 3800 hesitation. I than shift into second and just about floor it and the avcr reads + .5 bars of boost than the car knocks and hesitates and boot drops (cuttinf fuel agene) So deprest that my newest etempts faild i shift into 3rd and slow down a little. Than I hear a sound the loud sound of the turbo trying to spool. glance down at the AVC-r to see whats going on I notice the RPMs reading 0. Jus then the avcr slides off where I had it resting and I begine to put my foot in it and the car boost really well no cutting fuel. I took it out for a few more runs with the AVC-r set to limit boost at +.6 bars. i still have a reading of 0 for RPMs, and injector duty. I still have a TPS reading on teh AVC-r. I have checked all likely fueses and all are good. There is a posiblity that I have the AVC-r solonoid hooked up wrong (I was not sure where to get the lines from but I think its right.) What would cause me to lose the tak, injector duty, on the AVC-r, and no longer cut fuel at boost? and does any one have a pic of the corect way to hook up the solonid?

Thanks for all the help

wow my eyes are hurting, do you think you can sumarize that and myabe change pharagraphs or something please, im not trying to be sarcastic, that is really friggen hard to read

 

ok in short I did a JDM S5 swap on my 87 TII. It was cutting fuel than I lost the tack and injector duty readings on the apex AVC-r. and than the car started to boost with out cutting fuel. Why did it start boosting and why did I lose the readins on the AVC-r.

and pharagraph form:
