November 2021:

We are now offering Capacitor replacements for Trionic ECU's. 

This is because capacitors that are now 20+ yrs old will have lost their capacitance rating and have high internal resistance. Causing odd running behaviour and generally incorrect ECU sensor readings. Replacing the Caps resolves numerus running issues.

January 2022:

We have taken the decision to move all our Tuning capability purely into Trionic 5. This remains the highest demand area. Additionally with our tuning method of individual remap projects per customer it has been somewhat at a loss financially for T7 based cars.  Customers have often been disappointed with the power levels achievable on Trionic 7 and 8 cars (B2x5 and B2x7) due to the nature of the engines and the internal hardware upgrades needed to aim for big figures. Often of which can easily surpass the value of the car.

This is even more so with later B207 cars, where the GM Ecotec engine was never really designed for high BHP in mind. This can be achieved of course like anything, but at a high cost.

Moving fully into Trionic5 will make more time available to produce and market our "Multi Power Settings" kit. This will enable owners to Switch the power level of their car to 1 of 3 levels "In Real-time" just at the flick of a switch. Be it Low power (ideal for rainy / icy days), Medium power, or Full Power modes. The Multi Power mode mapping will be specific and require a full ECU remap. The wiring will then be supplied as part of an easy self install kit.

We are also increasing the cost of all remaps by £25 at this time. This is purely due to the amount of time it takes to compile the remap, processing Request forms, and taking into account ever increasing shipping costs which are all included in the total cost.

And finally, the T7  & T8 type APC valve upgrade is now to be included as a matter of course, unless the customer specifies otherwise. This includes the Software change, Driver Chip mod, and adding a Diode to the driver MOSFET to prevent feedback damage.

We are also replacing the Power Supply input Capacitor on every ECU we work on. This is due to the fact they are all faulty now at this age. Side effects of dead high resistance capacitors is poor injector timing, along with faulty O2 sensor readings and other odd ECU behaviour. We are using Panasonic branded Capacitors with a temp range of 102c. These are noted to be the best on the market.

August 2023:

Development News !.

Currently in testing is a special version of our popular EcoTorq tune, specifically for 95 RON E5 fuel. Such as found in Switzerland and a few other EU countries.

While it is not possible to get the same gains as 95 E10, however it should achieve +2mpg average gain while also giving 219bhp and 300nm of torque on a 2.3T.

With our modern boost curve profile it is possible to give big improvements to drivability when compared to the factory ECU programming.

Once testing is complete we will make this available to the general public. Approx November 2023

9th August BIG News update.
