muzzytt Posted August 21, 2013 Report Share Posted August 21, 2013 Hi all I just made my own patch harness , so I have plugged it in and no power ! I re checked and its wired as per the pdf file I got off the vipec site. http://forum.vi-pec.com/techdata/Toyota ... 8_Adpt.pdf when ignition Is on I have power on the C8 jumper which according to your wiring diagram is not connected to anything on the v88 side. a5 and b5 is connected to c16 pin which says ECU +12v supply EFI relay on the pin out it says switched power supply ? I'm confused about this. it also says c9 and c10 are linked so these two are connected to each other? ( I have soldered these two pins together) I connected the stock ecu and everything is working so what ever it is its v88 side. my email if that is better way to communicate is [email protected] :roll: Quote Link to comment Share on other sites More sharing options...
Scott Posted August 22, 2013 Report Share Posted August 22, 2013 Hi I have not setup one of these, so can only offer advice based upon what I'm reading. To me it looks like pin C9 needs to be linked to pin C10 to turn on the EFI relay. The output of this relay then comes to C16, carrying 12v+, that is used to power the Vi-PEC ECU. I would check the following: Does C9/C10 (now they are joined) have 12V+ when the ignition switch is in the on position? Does C16 have 12V+ on it when the ignition switch is in the on position? The answer to these questions will help us diagnose what is happening. Scott Quote Link to comment Share on other sites More sharing options...
muzzytt Posted August 23, 2013 Author Report Share Posted August 23, 2013 Hi scott Thanks for your time I'll go over everything again tonight I'm sure I've missed something . It sort of got me thinking when I finished the patch loom I cut short all the pins that where not used I'm thinking maybe I cut c9 and c10 effectively causing the problem. I'll confirm when I get home. Btw I'm going to go audi coils so I want direct fire instead of the wasted spark setup. Looking at the pdf ign 5 is used for something else in order to get 123456 should I just use another ign output to drive the coils? The o coils have built in ignitors Any input on this would be great. Thx Muz Quote Link to comment Share on other sites More sharing options...
Simon Posted August 23, 2013 Report Share Posted August 23, 2013 You will likely be able to move it to another drive no problem. So ignition 5 is free to do ignition. Quote Link to comment Share on other sites More sharing options...

The engine check light -ve is assigned to ign5 So i move that to ign 7 or 8 ? Cheers Quote Link to comment Share on other sites More sharing options...

muzzytt Posted August 31, 2013 Author Report Share Posted August 31, 2013 Hi guys Thanks for the input. That's sorted. Now I've got a question regarding the electric throttle. I still use the electric throttle however i installed a delete kit giving me full manual control of the throttle butterfly. The kit allowed the stock ecu to think it still controlled the throttle so it never threw up any codes or check engine lights. The stock ecu still was allowed to control the butterfly for idle control . Now my question is will i encounter any problems with this with the vipec v88. As i only need the vipec to control the throttle for idle duties. I'm presuming i won't have any issues. Any thoughts on this? Video explaining what i have done sorry in Japanese only but you get the drift. http://youtu.be/vUFxl9f9X88 Quote Link to comment Share on other sites More sharing options...
Simon Posted September 2, 2013 Report Share Posted September 2, 2013 If the factory system was happy im picking ours will be to as its looking for all the same signals. Quote Link to comment Share on other sites More sharing options...
muzzytt Posted September 8, 2013 Author Report Share Posted September 8, 2013 If the factory system was happy im picking ours will be to as its looking for all the same signals. Just to answer my own question today I got to fire up the engine, it started no problems. The throttle is working so far so good. I did only use the tps input that's wired together with the sub input. Not sure if this is a issue but when I turn igniton on the fuel pump is on and never stops is this how it is suppose to be? Also I have an AEM failsafe wideband uego kit wich input would I use to implement this failsafe ? I want to input the wideband so the vipec also reads realtime afrs from this guage. Cheers Muz Quote Link to comment Share on other sites More sharing options...
Simon Posted September 9, 2013 Report Share Posted September 9, 2013 You will need a AN volt free to take the AFR in put from the AEM. Quote Link to comment Share on other sites More sharing options...
muzzytt Posted September 9, 2013 Author Report Share Posted September 9, 2013 Simon Cheers. This poses the question should I disable the stock 02 sensor that's wired in as per the vipec pdf file posted above. I don't see the point of having two o2 sensors or am I wrong? Cheers Quote Link to comment Share on other sites More sharing options...
Simon Posted September 11, 2013 Report Share Posted September 11, 2013 Yeah not much point in having both. It's more typical to wire a wideband in replacing the original narrowband. Quote Link to comment Share on other sites More sharing options...
muzzytt Posted September 11, 2013 Author Report Share Posted September 11, 2013 cool aem is now wired in . I have wired in the blue failsafe wire into a spare aux input but no idea how to define it ? also any ideas on why the fuel pump is allways on even when you turn ignition on?

trd87t Posted September 11, 2013 Report Share Posted September 11, 2013 Go to the fuel pump output pin setup and turn the pullup resister opposite to what you have it now. This happened to me on as well on my first hookup. Quote Link to comment Share on other sites More sharing options...

This happened to me on as well on my first hookup. I went into aux output where the fuel pump is and there is no pull up resistor setting only polarity (low and Hi setting) Simon ?

trd87t Posted November 18, 2013 Report Share Posted November 18, 2013 I went into aux output where the fuel pump is and there is no pull up resistor setting only polarity (low and Hi setting) Simon ? That's probably it. I was thinking that it was going by another name. Have you tried to toggle between Low and High? Quote Link to comment Share on other sites More sharing options...

Hi mate, while ignition was on I went into the aux output that has fuel pump and turned that aux output off nothing happened fuel pump kept going . seems we have an issue somewhere else !

Simon Posted November 24, 2013 Report Share Posted November 24, 2013 You will need to check where the fuelpump control is wired in to the ECU. As I suspect its not on the AUX out you are expecting. Or there is a wiring issue somewhere else in the loom. Quote Link to comment Share on other sites More sharing options...

As I suspect its not on the AUX out you are expecting. Or there is a wiring issue somewhere else in the loom. Hi Simon I double checked the wiring a20 us connected to the fuel pump signal wire. A29 connected to the +5v. When I had stock ecu it all worked fine so a bit baffled. If I disconect A20 and leave a29 hooked up as per the wiring diagram the fuel pump is continually on. If I disconect a29 also fuel pump stops. In the New menu it has supra 1jz selected with polarity set high. I'll check out the wiring out near fuel pump something is not correct Quote Link to comment Share on other sites More sharing options...
muzzytt Posted December 17, 2013 Author Report Share Posted December 17, 2013 was looking through settings and noticed if fuel pump selected in aux 6 instead of 2 it gives more options than when aux 2 is selected is there a reason why ? I did wire it up as was in the vipec v88 wiring info pdf was that wrong ? if I was to wire directly to the new bosch relay wich aux output should I use to activate it ? cheers Quote Link to comment Share on other sites More sharing options...
Simon Posted December 17, 2013 Report Share Posted December 17, 2013 If you were to use a relay either drive will happily switch a ground to turn the relay on. The differences between the two drives will be due to the ability of drives 5-8 being able to high side drive so will have some extra options available. There is the chance the PDF is incorrect in this case. Quote Link to comment Share on other sites More sharing options...

muzzytt Posted February 11, 2014 Author Report Share Posted February 11, 2014 I just wanted to update this thread for future use. as you all know with ignition on fuel pump would continually run. well I hate to admit it after going over the wiring I realised I had aux 2 selected instead of aux 5. Im happy to report fuel pump turns off after the pre determined 3 seconds. case closed Quote Link to comment Share on other sites More sharing options...
