LS2 LQ9 Coil Installation

UPDATE – 420kw @ 24.5psi, big thanks to Rick @ Mojo performance and Glen @ ESP Racing Queanbeyan, dyno sheets listed below. This made another 30rwkw+ (40rwhp+) on very similar boost.

UPDATE 2 – Thanks to Steve at Torque Toyota for the attached diagram below of the 2JZGTE VVTi ignition wiring to match the Mojo kit.

UPDATE 3 – The car has since made 486kw @ 24.5psi on e85.

After many months of troubleshooting my ignition issues as seen in this post HERE I finally came to the realisation that the stock igniter setup wasn’t going to work with my requirements. I didn’t want any complicated aftermarket igniter or alternative solutions so I did some further research and came across the LS2 LQ9 kit from Mojo Performance. After reading some great reviews on supraforums –  I ended up purchasing them.

Rick from Mojo Performance was great to deal with, gave plenty of support and info and was very responsive via email considering the time differences between Australia and the US! In short it is a great bit of kit, easy to install, clear instructions and they resolved my ignition issues and I no longer have any break up of ignition on the road, although I’m yet to get back to the dyno and push it to it’s limits, this is where I used to get the worst issues.

Below is some basic installation steps on the kit for my 2JZGTE VVTi, I haven’t gone into the wiring too much as the diagrams are provided and will vary depending on your setup and aftermarket ECU, but there is the diagram above (See – UPDATE 2) to assist for stock setups . For those wanting to run the coils on the stock ECU you will need to purchase an additional module to generate an IGF signal for it to work correctly. The kit is available for 2JZGE and 2JZGTE non-vvti and vvti.

Some specific notes to my installation – I used the stock igniter wiring by cutting off the existing stock connector and soldering loom, I used the stock noise filter, I hid it away down near the front shock tower. The coils were wired in wasted spark, 3x ViPEC V88 ECU outputs used to drive them, this is possible as each coil has an igniter, but as always please refer to your specific ECU setup and wiring requirements. Currently running 3.5ms dwell.

This is the what is provided in the kit, all required hardware, quality wiring looms and instructions with wiring diagrams

Australia Day Drift and Show and Shine

One of my supra mates (TRD widebody with single turbo) invited me out to Sydney Motorsport Park for the launching of the new south circuit for the Australian Drifting Grand Prix and he also entered his car into a All Stars Show and Shine which was at the same event on Australia Day (26th January).

I’m not the biggest fan of drifting but it was a fun day out with plenty of variety of cars on display and some nice loud drifting 🙂

Cooma 1000m Sprint Results

Back in late October 2012 myself and some friends took our supras and other cars down to a 1000m sprint event organised at an airport in a regional town named Cooma which is in NSW Australia. I had gone to a similar event the year before and had great fun but also the car was just tuned and I was sorting out bugs, this year I still had ignition issues but car did run better top speed.

I managed a best run of 24.1 seconds @ 240kph and 27th out of 95 overall, bet the lambo so that’s all that matters! Another supra guy ended up with a 21.6 second and 281kph with a 3.4lt beast, which was the top speed of the day. 35′ GTR took out the top stop with a run of 20 seconds flat at 261.8kph due to pesky AWD!

Start line was really bad loose surface, bad 30kph head wind and also runway was slight uphill. Hopefully next year I can improve with all the bugs in the car sorted and the start line getting re-surfaced.

2JZGTE VVTi OBD Scanning and Information

While I had a stock engine and ECU I really strugged to find much information or tools to scan the 2JZGTE VVTi engine in my supra, standard OBDII tools did not seem to work. Some guys had tried and failed or got mixed results. I did find a guy in the UK that found out how, but it seemed one of his friends was a Toyota Mechanic and had access to an expensive scanner tool which wasn’t an option for me.

I’ve hopefully now found some basic information for the Toyota Supra 2JZGTE VVTi ECU;

-Is not OBDII compliant, it uses an JOBD compliant protocol as it’s a Japanese ECU –
-Uses a OBDII connector but requires a scan tool with correct software to read the correct protocol which is ISO 14230

It now seems like there is a cheap solution for reading the protocol; Thanks to Muzzytt on supraforums.com.au and Konrad on mkivsupra.net for sharing this information around on the forums.
