New Challenges

After racing my Eunos for two year, I decided it´s time to move to a faster car. I took a flight to the UK and drove home a Honda s2000, more to come...

Falkenberg Classic - WIN!

Last races for the year, new track, fast and short. And new to me. See me WIN!

SSM 2012 Knutstorp Race 2

The raceweekend of the year, SSM!

Good start again, but then almost hits the Lotus, which are unable to get into 2:nd gear.

My first podium, and I VERY proud to have the fastest laptime of all cars in this race on lap 7.

The raceweekend of the year, SSM!

Race 1 was a wet race, without any wet practise. I haven't had ANY wet driving with this car all year :)
Watch and see my DRIIIFT!

SPVM Kinnekulle 2012 Race 2

Race two on the first race weekend

Reversed top 6 grid gives exiting first laps. This time I didn't want to get stuck behind Per, so on Lap 5 Im going for it. After that I hunt Ronnie for the rest of the race. Big thanks to my sponsors.

SPVM Kinnekulle 2012 Race 1

First race of 2012

After a slow start I get stuck behind Per Oleskog, who defends hard. After some fair side-to-side racing, I get by him and cruise to the finish line. Big thanks to my sponsors.

Ready to race!

2012 Shakedown Sala Racing Park

Practise lap around the small circuit Sala Racing Park

Initial testing with all the winter changes proved good, cars work fine and has a little oversteery tendensies, which makes it alot of fun to drive! This in combination with 10% more torque (and even more then that at low revs) make the car so much more fun this year. Looking forward to go racing on a real track!

ECU Crystal mod with Dyno Results

Hi,

I own a 1995 Eunos Roadster 1.8L (Mazda Mx-5). Engine is unmodified except a cold air intake and different exhaust. This Swedish winter I have worked on improving the engine, and had the opportunity to also the to get bottom of this Crystal ECU mod. Here we go...

Last summer, I changed the crystal in the ECU, to raise the rev limiter by 5,75%. It worked good, but alot of discussion where whether it also gave some performance gain. Today I got results from dyno run with and without the crystal mod.

• I have two ECUs,
• The first one is an unmodified ECU from Japan (orginal in the car).
• The Second one I bought on ebay for ~€10. It from a 1995 Mx-5 sold in UK.
• I ran both without modification on the road, without any difference in feel what so ever.
• I replaced the original 8MHz crystal for a 8.47MHz crystal in the UK ECU.

Original ECU (Japan) dyno run

Crystal Modified (UK ) dyno run

As you can see, the result is quite clear, I did get more power. 

The only uncertainty in this test is that we didn't test this with the same ECU hardware, but the software in the ECU was checked and is identical. 

Conclusion

Either the hardware is different (unlikely) or the Crystal mod does work both for raising the revlimiter and give you some extra horse power, almost for free.
