Trying to decide on what I need to tune and monitor my motor. It has TD04 turbos, Nismo 555 injectors, forged bottom end etc etc. The left turbo has been drilled and tapped for a egt probe, so I was thinking about running an egt gauge for the left bank, putting a wideband on the right bank and installing a gauge type boost controller. I'm planning on running a Nistuned ECU. Anything I'm missing? I figure if I'm watching temp on one bank and AFR on the other I should have a good idea of what's going on. Does anyone have any product recommendations? I'm completely undecided and unbiased as far as different brands go. I don't want to spend a fortune though.
To do it properly you should have one of each on each bank, or at least wideband sensors on each bank. Our engines are essentially two 3 cylinder engines bolted together. Just because you're seeing good lambda figures on one bank doesn't mean the other is seeing the same.
Wouldn't bother with lambda or EGT. Just get oil temp, oil pressure and water temperature together in a din slot or similar and an eBoost for boost readout and boost control.
I know two widebands would be preferable, but they are pretty expensive. I know a lot of people only run one wideband on v8s, so I figure having an egt on the other side is a step up on that. It will still have narrow bands on each side for the ecu which I can monitor too. Unless you know of a cheapish dual wideband set up...
Oil temp is probably a good idea, especially since my turbos don't have water cooling... I was considering removing the factory water temperature gauge and trying to get an aftermarket gauge in the cluster, it could be kind of cool to put oil temp In the factory fuel gauge position and fit a fuel gauge elsewhere. Regarding oil pressure, I was told installing the 350z sensor makes the factory gauge more reliable and accurate, so was planning on doing that.
so is a melted piston. narrowbands don't tell you shit. They're only purpose is for ecu closed loop control at lower rpm/throttle position running. On a turbo car, I'd go a decent knock sensor system before I worried about egt's, unless you're running e85 :br:
I won't be running e85 at this stage on 555 injectors, but never say never What sort of knock sensor systems are you referring to? I know the factory knock sensor gets ignored after 3k rpm, but I haven't come across any aftermarket set ups, not that I have really looked into it.
I feel I should also mention it's not going to be a racecar, so full load high revs won't be too frequent... Maybe... The other thing I was wondering was what a good tuner will need to get the car set up properly? Again, two widebands is probably best... Need to find a good tuning shop in Melbourne that does Nistune
Unless you are tuning yourself you dont need widebands or knock detection. Let the tuner do that and you just focus on coolant temp, oil pressure and boost. Dont run more boost than it is tuned for.
Agree, but make sure whoever you do get to tune it does have a decent knock detection system. If they tell you they don't need it cause the can hear ping with their ears, run
