The ecu map and fuel pump and injectors also have a large bearing on the torque gains you'll get.Ī longer valve duration can alter the torque band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations. You should ideally match your power band to your preferences so for a car used daily stick with a fast road VQ30DE-K camshaftĭifferent VQ30DE-K engines respond better to less aggressive camshaft durations so set your engine up on a rolling road. This is because a competition cam causes a very lumpy idle, and makes the car more prone to stall or jerk along in stop start traffic, sadly though many ignore this and end up ruining a perfectly good car and having to revert back to a fast road, or OEM cam profile. Motorsport cams, raise the top end band but as a result the car will not idle smoothly and low end power nearly always suffers.Ī Motorsport and race camshaft makes it harder when driving around busy urban areas. Choosing a higher performance cam profile raises the power band accordingly.įast road cams usually raise the bhp and torque across the rpm range, you could drop a little low end bhp but top end will be better. Just because particular parts are popular with VQ30DE-K owners it doesn't mean you should fit it, we shall concentrate on the greatest parts that will give your VQ30DE-K the biggest power gain return for your cash.Īltering your VQ30DE-K cam will make a dramatic difference to the engine power band. Tuning the Nissan VQ30DE-K and best VQ30DE-K performance parts. This is based on the VQ30DE and the suffixed -K denotes improvements and the VQ30DE-K has an innovative intake manifold (not on US models though) which gave better performance and the engine was more efficient overall. History, Power & Specs of the VQ30DE-K Engine
Nissan maxima ecu tuning mods#
Our aim here is to detail the best approach to VQ30DE-K tuning and show the greatest mods that work. The VQ platform is V6 and capacity ranged from 2.0 to 4.0 and engines were adopted by Renault and even formed the basis for Nissan's race engines - the VQ30DETT VQ engines appeared from 1994 and has won awards pretty much every year since then. The Nissan VQ30DE-K great bases for a tuning project and with carefully chosen tuning tuning mods like a remap, turbo improvements and camshafts you will positively maximise your driving opportunities. Stock EPROM back in for now, ready for custom tunes! Just waiting on a few more parts in the mail before the process begins."All you need to know about performance tuning the Nissan VQ30DE-K engine!"
Still needs a little clean up before the new socket goes in.Ģ8 pin DIP socket installed in the board and good to go! Be careful when it's apart! Static damage and physical damage alike will can the board!Ĭlose-up of the desoldered traces. So here's the Pathfinders ECU once you remove the lid and desolder the stock EPROM IC. There is some serious untapped power and economy with my setup so it's time to tune the pathfinder! I will also be getting rid of the seriously tiny stock maf and using a massive N60 Maxima maf and modifying a modern vg33e intake manifold/65mm throttle body. All this is running on a stock Pathfinder 3.0 fuel system and tune and frankly it's not keeping up. VG30E cams, high flow custom intake, OBX headers, 2.5" custom exhaust (hi-flo magnaflow cat/flowmaster muffler). I've got a 1993 Pathfinder with a VG33E swap. Well I just finished getting the 240SX all up and running on a custom tuned ECU, got it all ready for the turbo setup.
