AVO Turboworld's custom ECU Tune to match their Ceramic Coated Catless exhaust manifold, found here.
The key combination to the Header is the ECU Tune as the vehicle runs lambda all the way to redline, therefore meaning that without a tune the Headers will practically make no difference in power. AVO adjusts the engine parameters to get the optimal performance out of this 1.5L engine by keeping the AFR and Exhaust Temperatures in a safe and reliable area and combined with less back pressure in the exhaust translates to an increase in engine performance of 11.3 kilowatts at the wheels from stock. The power increase out on the road makes the car feel sharper and more responsive and better than you think because of the power to weight of the Suzuki Jimny.
This AVO Catted Header & Tune improves the horsepower from the stock figure of 47.3 kilowatts at the wheels to 58.6 kilowatts at the wheels. This is close to a 24% increase in power and the thing that is even more impressive was the 25% increase in torque range from 3000 rpm to 5000rpm.
Please note that the ECU needs to be shipped to Melbourne to be bench Flashed. To be able to remove the ECU then you must do the following:
Check to see Vehicle has any DTC's
Clear DTC's if there are any
