Thought I would do a write up on a recent mapping session with Will, aka âEK9Turboâ at RDT near Doncaster.
Drove a fair old way to get there. My EK9 is a 1998 almost standard 1600 with 95k miles on it. It runs a JDM 4-1 manifold with Mugen twin loop utilising the standard JDM cat. Only other mod is a K and N filter. Although its a high mileage car its always been well looked after mechanically. I had fresh Mobil1 0 -40 oil and fresh Landrover MTF94 in the box.
First off Will checked the tyre pressures then put the car on the DynoJet to check car out. Four or 5 runs demonstrated the repeatability in various gears and we had our baseline measurement to me then off to his workshop.
Will then went through a number of things what he called a pre dyno health check. Engine compression, Then valve gap adjustment showed I had a couple of tight ones and a couple of loose ones. Nothing too far out of spec So all sorted fresh set of plugs and mechanical Ignition timing set He then installed my S300 which was a Limited Edition S300 OBD2a so no conversion harness required either. Will then proceeded to wire in a good earth and power source for the wideband all very professionally done. Checked tyre pressures were at the pressure I use. Even fixed a leak on my VTEC solenoid. He installed a good base map that he has developed for the EK9 and fitted a temp Air Fuel ratio gauge to the car. Then we headed back to the Dyno
Spent the best part of 3 hours on the DynoJet with Will doing lots of runs and steady state tuning across the whole rpm range. I said I wanted a good mid range and not chase big numbers. Been there done that.
Drove the car back to the workshop to check it all over again and the transformation was truly unbelievable. The crispness of the engine is sublime. The throttle roll on roll off is so smooth. The car pulls like a train. Acceleration through the gears is transformational. The car makes power from much lower down than it ever did before. I can honestly say he has transformed the characteristics of the engine in the best possible way.
I have personal experience of 3 other Mappers in the UK and I also own a fully tuned B18C6 in a CRX running Omex 600 engine management and can honestly say this was the best experience I have ever had in this field.
I cant recommend Will highly enough I had a round trip of 350 miles finished driving back through the snow and still say it was worth every penny.
Results were 170 whp and 113 lb/tq
Graph below I used one that compares mine with a good completely standard EK9 that Will mapped previously with a Hondata S300 to show the improvements.
