Last time we spoke about having the Nitron suspension set up, new cambelt, water pump and more.
Now it is time to tell you about the new ECU fitted and Mapped by Abbey Motorsport.
We decided to go far above the base install that the Link G4 offers.Power is nothing without control so they say.
The spec list for Project Moff is now huge, and we have recently updated it.
What other Engine ECU options were there ?
There are a number of ECU’s on the market we could have used, such as OMEX 710 Series ECU, Syvecs, Motec, AEM and more.
Why did we choose Link G4+ (G4 Plus) ?
Very simply because we have read a lot of good reviews, seems compatible with everything we wanted to do.
What did we do ?
Firstly the new 800CC Injectors from ASNU were fitted
To make sure the extra fuel needed was supplied, a Walbro GST450 (450 litre per hour rated) fuel pump was fitted. Not the most exciting item to look at !
The New Link G4 Ecu with fitted in to the old Standard ECU casing
Link 4 ECU – with boost control, EGT sensor (Exhaust Gas Temperature), Inlet air temp, oil pressure, oil temp, water temp, fuel pressure, lambda controller and AEM Trigger wheel. 12 position trim switch for boost settings.
Why did we fit these extra sensors to our Link G4 ?
We wanted to add an extra level of protection and peace of mind to the engine, on the basis that the ECU would have more control over engine parameters in case of any issues.
EGT sensor (Exhaust Gas temperature)
Oil and Fuel pressure sensors
Air temp sensors
Wideband AFR (Air Fuel Ratio)
The link G4 is also going to control the boost too.
What do all these sensors do ?
All these extra sensors link directly back in to the ECU. Should the ECU detect paramters which fall outside what has been programmed the norm, then the Link G4 will cut engine revs, reduce power to protect itself. For example, if the oil pressure detected is too low, then the ECU kicks in and will cut the engine revs to 500 whilst at speed. If it switched the engine off completely whilst on track, then we then have danger to the driver, so there is a fine line to consider !
How much do all these extra sensors cost ?
To wire up the ECU neatly, and all the additional sensors, was an extra 2 days to get it looking as tidy as it does.
Now for the exciting bit, car could get on the dyno !
All in all the car was on the Dyno for around 8 hours.
The max boost was set to 1.6 Bar. Here is a short video of a dyno pull in 4th gear at 1.4 bar.
This dyno video shows the car making around 625 BHP at the rear hubs (2nd figure down on the far right. To the left is the torque figure)
Probably the best part is the adjustable boost settings we have. This is because it going from 0 -11. Everyone needs a knob that goes to 11.
More info on the fitting the new dash here.
Why do we have adjustable boost settings ?
Mainly to control the power. There is no point running at full power all the time. Especially in the wet, or when we are warming up the car. It will also help with reducing the engine wear !
What are the different power settings ?
The car goes from 435 to 653 BHP at the rear hubs depending on where we turn the knob to !
What were the peak Dyno figures ?
At 1.6 Bar Turbo Boost pressure
Peak Power 653 BHP @ 7647 Revs @ Hubs
Peak Torque 492 lb/ft @ 5837 Revs @ Hubs
Here are the Dyno sheets
Needless to say, we are very excited to use the car on the race track soon !
Another fantasitc benefit we now also have with the Link G4, is hte fact we can go back after a track day / race day / dyno session and download the logs (they can be seen in real time too). From this we can see if the map neds to be tweaked, if there are any unwanted variables, or to help improve driving. The logs give us everything !
