Always want to learn more from the experts and their opinions based upon their years of experience. This YouTube video appeared in my feed. Not saying that I understand any of the this except that it makes sense when you consider that oil additives wear out or break down. I did make note that timing chains are attributed as a factor for the shearing impact upon the oil additives. I am still thinking that it comes back to using a quality known brand engine oil and an appropriate oil change interval for your specific vehicle and driving conditions. -
Hi there just after some advice on replacing my radio. Toyota can’t upgrade my maps so I want to replace the unit. Any recommendations on aftermarket head units? Thanks -
Got a good chance a month a go to give the beast a good wash. Sydney weather and the usual weekend jobs have stopped me from cleaning since but I also got a good chance to top up the HydrO2 coating. Decided to go for some quick shots not to far away from home. For a few months now, the car has been running a bit rough in terms of the tune. I had noticed for some time it seemed to be running quite rich, especially on cold starts where it would run as rich as 10.7:1 where as it would normally start in the mid 12:1s before. It was also showing random signs of hesitation on partial throttle in particular and occasionally moments of full throttle from a stop. All of this resulted in some pretty poor fuel consumption amongst other things but I caught up with Adam and did some logging and tuning last week to sort out the issues. After doing some driving and logging, Adam could definitely see the car was running way too rich. When checking through the tune, he also adjusted the temperature settings which now read correctly to not stop me from revving out all the way, especially when in stop start traffic or letting the car sit for some time with the engine bay heat. The main cause of the issues I was having was that the open loop tune was tuned to run too rich and the closed loop tune was over correcting too much which caused the sudden hesitation and throttle input delays. Once the open loop was corrected, the closed loop was re-enabled and the manifold pressure settings changed for when closed loop would take over as this reading was set too low. After addressing the concerns, the VVT and Lift tune was adjusted accordingly. Lift was set at 5500 RPM and has been raised to 5700 RPM and it honestly feels much better. Since the exhaust uses a 4-1 header/extractor, it really gets going in the higher parts of the rev range. Raising lift 200 RPM to 5700 RPM actually reduced the dip from small to large cam and the car feels much more linear now. After the hours of logging and tuning, it was a great result to have the car much more driveable at lower revs and singing all the way to redline when giving it a boot full. -
Hi Lou, I have a 1995 one, and it is registered as a classic. Any vehicle older than 25 years is considered a classic, so , since yours is about 26 years old it is a classic. That info is for Victoria, but I would assume the same in Qld. Herb -
