ECU maps

Uprated/tuned Nissan Z32 300zx Twin Turbo ECU maps

Following the closure of SE Nissan/NissTek, I have purchased the rights to the ECU maps they developed for and sold to, their customers. Each one is the product of testing and development on different engine specifications and gave good results for those vehicles. A number of maps are available but I have identified ones that will be most suitable for the majority of road cars. The more specialised maps would need careful consideration and discussion to determine whether the car matches the specification of the cars that were originally used for the dyno development.

ECU Map One:

Available as a manual or automatic version. This map suits engines of original internal specification with minor modifications.

	free flowing air filter
	free flowing, un-restrictive exhaust
	catalytic converters removed
	raised boost pressure (absolute maximum of 1.2bar, 1.0bar recommended)

ECU Map Two:

Available as a manual or automatic version. This map suits engines of original internal specification with minor modifications.

	free flowing air filter
	catalytic converters removed
	raised boost pressure (absolute maximum of 1.2bar, 1.0bar recommended)
	This map has been modified to suit engines with a slightly restrictive exhaust (e.g. Mongoose), or other problems leading to detonation at higher rpm/boost.

ECU Map Three:

Suitable for engines with internal modifications (e.g. forged pistons with lower compression ratio – 8.1:1). Tested on a manual gearbox only.

	555cc injectors
	free flowing air filter
	free flowing, un-restrictive exhaust
	catalytic converters removed
	raised boost pressure (absolute maximum of 1.2bar, 1.0bar recommended)

I ran ECU Map Two on my car and had the opportunity to do a back to back dyno test with a JWT chip with the following results. Due to variations in dynos the actual numbers are less important than the difference between the two runs, which as you can see, are significant.

Installation & Tuning

	It is essential to select a map which most closely matches your engine specification. Optimum performance will be gained from the best match between map and engine, fitting a higher spec. map than the engine spec. will result in less performance and may result in engine damage.
	No specific power claims are made as it will vary car by car, but judging from the comparison made with the JWT map, it could be expected to be equal or better.
	The majority of the power gains are from raised boost, the fuelling and ignition settings in the map make it safer to run that increased boost.
	Installation and use remains the risk and responsibility of the owner, all tuning steps should be checked to ensure no detonation is present and requires continuous monitoring of engine behaviour.
	You should ensure that the car is in fine condition before embarking on any tuning.
	Careful monitoring of boost pressure is essential. An accurate, after-market boost gauge should be installed or a boost controller with a built-in boost gauge.
	Boost jets are not provided due to the variation between different cars. A 1.2mm jet may give 12psi on one car and 15psi on another.
	All maps assume the base idle timing is set at the standard 15deg BTDC

General information & benefits

	The maps were developed on standard UK unleaded fuel, giving a safety margin when running on super unleaded (eg. Shell Optimax). Note: this is not a compromise for either US or Japanese fuel. You should always use Optimax for best performance and safety
	These maps are not based on JWT or any other tuners work. The base code was a late model Nissan map with all developments made from that point onwards.
	This modification also removes the 112mph (180Kph) ECU based speed limiter on Japanese imports and 155mph speed limiter on UK cars.
	Rev limit raised 200rpm
	Better throttle response
	Improved BHP and torque
	The map will be supplied on a 256Kb 28 pin DIL EPROM with suitable static precautions
	It is essential that appropriate anti-static precautions are taken during installation of these sensitive devices.
	You should notify you insurer following a modification such as this

Various guides are available online that describe installation of boost controllers and bleed jets. Eg

If your ECU needs to be socketed that can be provided as an additional service, which can include Royal Mail “Next Day” return postage, or can be done whilst you wait if you are able to visit my house in Essex. Your original Nissan chip will be included, should you wish to return the car to standard. For further details please send an email using the link below.

The cost of each map is only £60 incl. postage

The cost to socket an ECU is £30 + return postage, which is currently £6.95 for Royal Mail 'Next Day' service.

Payment is possible via PayPal, cheque, bank transfer or plain old hard cash !
