Update?

Sorry been slack on the updates unfortunately. Lots of changes since i last posted. Ecu change, tuner change, added a second nitrous kit, a few more sensors and chased converter setups all year. Ran it hard for around 10 roll race meetings at no less than 1000hp and as much as 1400 with all the nitrous. We were using these roll race events to iron out bugs and evaluate changes to transmission and torque converter setup all while having alot of fun doing passenger rides and racing door to door. She still hasn't been down the strip as i felt the converter combination wasn't quite where i wanted it to be.

End of 2018 we removed the M150 as the GPR software was strangling us and we consider going down the custom firmware route but decided a Emtron would do everything we wanted right out of the box so i repined the wiring harness and have absolutely loved the change. The car made 1100 at the hubs on about 35psi on the 7685 Gen 1. With the progressive direct port kit 1340 on the same 35psi. We pulled the engine mid last year to do a bearing check and upgrade the turbo but after much thinking decided the cast block would be on borrowed time where we were headed so we gave it a new set of bearings and sold the complete short to a mate for his project. The money from the sold short engine has funded a new billet 3.2 combination that's going together currently. New turbo is a GTX55 91mm on a 6boost manifold. 

One device we found very handy was the performance meter Dragy, it made tracking changes to suspension, tyre pressure, tune very easy. Even with 4 x 275/60 radial pro's power management is a absolute must on a slippery track. With no nitrous completely untested setup we were doing 100-200kmh mid to high 3's, suspension tweaks and tyre pressure dropped to around 3.30's, 125hp Single nozzle nitrous kit around 3.15's, no passenger just over 3's then with direct port kit and more suspension tweaks just under 2.70. As a example a mates barra VL ran 2.99 on a 8.12 170mph pass so we were pretty happy with our result on a non prep'd surface. 

Fingers crossed ill have a engine to install in the coming month and hopefully keep this thread updated with a few new pics and some info.

It is a bit of a shame Motec left the GPR packages quite basic considering how powerful they are, it sells the platform very short.  You really shouldn't have to change to an Emtron to get what you need from it - though I love how well sorted Emtron are out of the box.   Just for interest if you (not sure if you meant developing a custom package, or getting a pre-existing one) or others didn't know, there is a GT-R package for the Motec M1 which is very very capable: https://powertune.com.au/2019/07/12/m1-nissan-skyline-32-34-gtr-rb26-package/

Car sounds like it is going very very well, and I agree with the Dragy - we have a couple and have used them for similar testing/tuning.  I look forward to seeing how it goes once you hit the strip

I made contact with a package developer and after a lot emails and thinking it definitely didnt fit my budget or time frames. Would've hated to be at the track and required tweaking. A right click on a axis sounded way easier to me lol

Engine is close to being finished ill post pictures of that soon. Once i get that back full steam ahead.
