This is the crux of it, big fan of Nistune but I was probably asking way too much of it in the timeframe I had (or wanted) to get it sorted. Matt from NT had been extremely helpful but in the end I decided to move to a full stand alone system. As I’m keen to run this on both E85 and PULP Haltech with its new flex fuel sensor makes a lot of sense.
So anyway time for an update, i’ve been incredibly lazy (well not really, new kid, shitbox rally (Brisbane, Adelaide, Ayres Rock – Perth) and my other project car (1UZ 5-speed bluebird)).
But as for this POS unfortunately Haltech ECU's wont work out of the box on a VQ30DET - easiest way to to resolve this issue is a custom 36-1 trigger wheel.
So i had one machined up.
Which ended up as this (interference fit on crank pulley).
Then attached with M5 bolts, tooth removed and painted.
And finally installed with raised sensor platforms.
ECU installation – Early progress… going for a stealth installation.
And as of this week ECU has been powered up & upgraded to lastest Haltech firmware.
Wired and tested:
- Air temp sensor
- Coolant temp sensor
- TPS
- Ethanol sensor (tested with some old EFLEX, 68% - magic little box)
- Crank trigger
- Fan switching
- Clutch switch
- Fuel pump relays
- Boost control
- Shift light
- WB O2 sensor
Wired but untested:
- IAC (4-wire idle stepper motor)
- Ignition coils (12v power source OK)
- Injectors (12v power source OK)
- External MAP sensor
- Digital tacho synchroniser (6 cyl ECU outout – conversion box - 4 cyl dash tacho)
- High/low boost switch
Skid time is fast approaching
