Nissan Cefiro with 2JZ GTE VVT-i + Adaptronic e420d

An owner of a Nissan Cefiro with 2JZ transplant want a better performance from his stock 2JZ motor.We fitted and tuned his engine with Adaptronic e420d ecu.

Stock engine,0.95 bar boost tapering to 0.85 bar at redline,the sequential twin turbo have been converted to parellel operation and drive by wire throttle body (ETCS-i) have been disabled. 

Final result,base run and optimized.We having problems with initial boost response after a few run due to boost control system unstable but manage to find a bit more top end torque and power.

Toyota Corolla SEG 4WD with 4AGE 20V + Adaptronic e420d

This Corolla SEG 4WD is a very rare car in Malaysia,this unit is fully imported from Japan.

The car have original 4AGE 20v fitted from factory and a 4WD transmission.Due to the 4WD the power output at the wheels is very much lower than the 2WD version.This car has been fitted with 272 cams and 4-2-1 extractor.Adaptronic ecu was chosen for engine management.

Untuned vs tuned,huge increase,but still pretty much lower than its 2WD counterpart.We guess that the transmission taking so much power from the engine.

Toyota Corolla AE101 with 4age 20v + E-manage Ultimate

Final result of this tuning.Again this is a healthy engine with this sorts of power output.Engine is stock except for an aftermarket 4-1 extractor.

Toyota Corolla SEG with 4AGE 20V Blacktop + E-manage Blue.

Hi,we have another 4ag 20v with e-manage coming.The e-manage is very popular with automotive enthusiasts in engine tuning.

 Stock engine.

End result,green is before and red is after tuned,this is normal HP output for stock healthy engine.Car should go much faster with 15 inch wheels rather than 16 inch the owner is using now. :)

Mazda MX-5 Miata + Adaptronic Plug in ECU

We have our second MX5 Miata come for tuning. Its a 1.8 liter model with 6 speed transmission.

Engine bay,stock engine with extractor and adjustable camshaft pulley on both intake and exhaust

Final results after advancing the intake cam. Stock horsepower was about 96whp. Very huge gains by using the Adaptronic ecu alone.This engine can take quite a lot of timing from stock.The owner does gymkhana with this car and he love to low end torque improvement.

Toyota Corolla KE70 with 4AGTE + Adaptronic e420d engine tuning

Hi,we have another 4AGTE coming in. This time it is in RWD form.

The engine bay,stock 4AGZE long block engine with S15 silvia OEM turbo,440cc injectors,coils,igniters and intercoolers are from Mitsubishi . Engine management is Adaptronic e420d

Once again,old is gold.

This what we achieved,203whp at 0.9 bar of boost (tapering to 0.7 at 8000rpm redline),we run out of injectors at 1 bar.The curve is good,it feels very quick and have no traction issues. It leave my JZX90 in  dusts on 3rd gear pull.

Toyota Corolla SE with 4AGTE + Adaptronic e420d tuning

Hi,first entry in 6 months time.Been very busy to update this blog but here we go.

 Old but don't underestimate what it could do

Here is the final figure. 1.4 Bar of boost and capable of revving to 9000rpm in a small light car is fun,just need find better traction though. Through AFR and ignition tune we manage to better the original tune especially at the top end power and torque. This engine is pretty durable,for an old small motor,it is amazing its still holding up. And we haven't really run it on full boost yet (1.8 bar capable). Turbo is T04E,stock 4AGZE bottom.

4AGE 20V + Adaptronic e420d + Toda 264-264 cam

One of R.N.R Autosport customer have upgraded his machine.Previously it was stock 20v Blacktop with metal head gasket and adjustable cam pulley on exhaust,was run by Adaptronic e420d ecu with R.N.R Autosport  COP conversion kit.

The owner have upgraded his cam to Toda 264-264 9mm lift.Others remain untouched,even the piston is OEM 81mm. OEM Rotating internals have been balanced.

The blue graph is Toda Cam run with previous tune,the red graph is Toda Cam after tuning the ecu,the power drop above 8000rpm is due to cam settings,the owner will send the car to his mechanic to optimize the cam timing and hit the dyno again.The VVT is still retained in this setup.The gain is almost 9HP, i reckon it can get more than 160HP on this dyno with proper cam dialing setup.

Fuel is RON97 with Octane booster.
