Lamborghini twin-turbo project details:

We decided to throw two turbo's onto a Gallardo , using the Unichip to tell the stock ECU to make it all work . The Unichip controls two intelligent injector drivers which control 5 extra injectors each. The Unichip fires the 10 extra injectors (full sequential) synchronized to the original ones to keep the traction control and rev limiter functions working correctly.

One Unichip controls the injector drivers, the timing, the original load signal (clamping etc), drive by wire is controlled by the TPS in and out (mostly to create backfiring on overrun) 0-5V 1 is used for launch control (but it turned out there is no need for launch control since it lights the wheels effortlessly in 1st, 2nd, 3rd and even gets the traction control flashing and cutting cylinders throughout the whole of 4th gear spinning the wheels at 145mph !! One of the auxiliary outputs (Option 1) switches on medium boost (14.7psi) with internal driver and auxiliary output. Auxiliary output 2 (Option 2) switches on intercooler water spray through an external Unichip driver in front. Another auxiliary output (Option 3) controls the water injection solenoid through a driver in an external mounted Turbo module. Auxiliary output (Option 4) switches on water pumps through an external driver.

Auxiliary output 5 (Option 5) switches on high boost through one of the internal drivers (option 5 driver) One of the Unichip inputs monitors the original injector on time which is used for intelligent foolproof CAT simulation, The Unichip also monitors the air temp to help things run smoothly. The Unichip built-in Lambda simulator is used to simulate CAT temp sensor signals to both ECUs. The Lambda input on the Unichip is used to log AFR with Unichip lambda meters.

The Lamborghini project is not your average project

We must admit this is the first time we ever used all the functions on a Unichip, in fact we had to use a second Unichip to control the transmission, doing exhaust pressure pulse simulation (The OEM monitors this as misfire detection) and to control the drive by wire on the second bank for backfire generation on overrun.

To tune it we only ran it under load up to 4500 RPM with 8.7psi boost. We got it to be correct there and simply guessed the rest of the values. Then we ran it with pure inertia and spot checked the settings. Even with a pure inertia run on one of our Unichip 4x4 dyno's we had to add 700 lbs (one tuner & three wide-eyed journalists) to the weight of the vehicle to prevent it from wheel spin in 4th gear. For cooling we ran 4 fans totaling 24hp of power with custom made ducts for the front units. 7 Tie-downs to keep it in place! The tuning is not 100% at the time of the video but the AFR stays between 12.0 and 11 in most places under boost. With the kind of power on tap no-one will be able to tell the difference. Once we are happy with the tuning we will turn up the boost to 23.2psi (only on the dyno) to see what we get out of it. We will do a video of the run. If it survives the ordeal I will probably spend a bit more time on the fine tuning. so check back soon for updates.

Please note : The turbo kit for the Gallardo is not a production kit & will NOT be available through Unichip , the project was done purely to demonstrate the superiority of the Unichip over any other tuning tool.
