Well,
been a very busy time, but managed to get some more pics of some of the things ROOBY has had done over the last little while.
Fiting the supercharger a little while ago created some issues with the knock sensors on the engine, bringing on the check engine light, and default backed off timing on the computer, which didnt help power, or economy, and to overcome the issues, we have now fitted a microtech computer piggy backed with the original ECU so cold idle, A/C idle up, and auto shifting etc is all controlled by the factory ecu, and the microtech does the rest.
The supercharger is a CAPA kit, with V1 Vortech unit [that needs a new rubber hose from the unit to the piping we made, and the soap doesnt like the paint we painted the pipe with either.] I was going to turbo the car originally, but when this kit came along at a price to good to refuse second hand, I thought it was worth trying.
Microtech havent had the best name in the past, as being very simple units, but when tuned with the laptop and microtech software, you get double the plot points to set at for timing/fuel etc, and running it piggy backed to the factory ECU to control the other parts we wanted.
Currently, the 5200 rpm readline sees the kw and nm still climbing and not tapering off pulling 9 psi of boost. [should be a 6.5 psi kit and pulley] so we have gone 2 heat ranges cooler in the spark plugs, but an intercooler may be next, to prevent detonation, rising intake temps.
We have also installed a Malpassi rising rate fuel reg, and Bosch fuel pump, to stop the injectors going onto max duty cycle. [reg with fuel pressure gauge fitted below] as wella s a vn air temp sensor in the pipes after the supercharger, and a second toyota coolant temp sensor, as we couldnt piggy back that voltage to both units, so we gave them a sensor each.
On 37's we are seeing 182kw and 608Nm [aprox] at the rear wheels, and on the hwy economy seems to be slightly better than standard 4.5 while pushing the 37"s. Did a high country snow trip with Craigs group 2 weekends ago, and at alititude, on the hwy, general driving around, the extra torque has been really nice.
Holding the foot flat on the road and letting the ecu shift second has created an issue with the vehicle spinning the left hand front 37 " tyre as it bangs second gear though, so a 2wd/4wd conversion is next, as the car is also spinning the fronts when driving/cornering more spirited than normal, even up to 80kph+.
