Falcman007 100 Posted July 16, 2017 gday guys, So the ED is now manual. My problem is it runs fine, accelerates fine BUT taking the foot off to slow down it jerks pretty bad. It is still running the auto ECU. I have a J3 to be tuned to suit soon. thanks Kim Share this post Link to post Share on other sites
gerg 10,871 Posted July 16, 2017 I managed to use an auto ECU with some resistors soldered into the gear position sensor to fool the computer into thinking it was in "D". Can't remember what resistance it was but made a difference to the jerkiness. I never cured the fast idle issue until I modified the ISC valve.Sounds like a tuning issue with fuel mapping, as in the point where it goes from closed to open loop, etc. Sent from my CPH1607 using Tapatalk Share this post Link to post Share on other sites
Falcman007 100 Posted July 16, 2017 Thanks gerg. I bought the resistors, 1 watt 6.8 k and 1.2 k. Apparently I need to hook up the nutruel switch on the box for other issues, I figured if it gets a tune it wont need them. i actually just got my J3 back, plugged it in and the fuel pump doesnt stop priming and the car will not start. Removed it and it starts. Share this post Link to post Share on other sites
Drew442 67 Posted July 16, 2017 Pump keeps priming means the flash is bad. Either for the wrong box or just corrupt. Who flashed it? Sent from my MI 5 using Tapatalk 1 Valvebouncer reacted to this Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted July 16, 2017 Is the harness significantly different from a manual to an auto? Or is it a plug in section from factory?Found this, not sure if it helps.https://www.tiperformance.com.au/knowledge-base/wiring-up-the-neutral-switch-in-a-ford-falcon-manual-conversion/What drew said is spot on, I've read somewhere too that if the pump keeps priming the chip is corrupt.

gerg 10,871 Posted July 16, 2017 ISC valve?Idle Speed Control. Lives on top of the throttle body. I drilled and tapped a tapered bolt into the side of it that limits the travel of the plunger inside. Instead of 1500, I got it idling sweet at 850. It also used to hang up between gear shifts but this fixed it. Backyard mechanics at its best lolSent from my CPH1607 using Tapatalk 2 SirkWhyXF and XPT reacted to this Share this post Link to post Share on other sites
Gav 616 Posted July 16, 2017 I'd read the " extra tips" in the installation notes. They explicitly state that improperly cleaned ECU contacts are a cause of fuel pump priming issues. Make sure the contacts are clean because it's the first thing they will tell you to do when you make contact with them. I've used their product without issue. I made sure the ECU contacts were fastidiously prepared before I inserted the chip......give it a go and see how things run then... 1 Drew442 reacted to this Share this post Link to post Share on other sites
Drew442 67 Posted July 16, 2017 There's no need to modify the isc valve. You can program the desired rpm in the chip.You only need to do something with the neutral safety switch in the loom when you swap to manual with an auto ecu. Vss is the same.I'll fix that typo in my last post too.Did you get one of the chips shipped out last Sunday? I noticed on Instagram Jason say he had quite a few to do, maybe he made a mistake?Sent from my MI 5 using Tapatalk Share this post Link to post Share on other sites

Falcman007 100 Posted July 16, 2017 cheers guys. And TI performance have a great rep. This is just a minor issue hopefully on my part. Ive spoke to TI and they have been very good regarding the problem. I'll give it another good clean up and see how i go. Thanks for the help. kim Share this post Link to post Share on other sites

I don't think you'll have any trouble sorting this out if it's a problem on their side.Sent from my MI 5 using Tapatalk Share this post Link to post Share on other sites
