SUZUKI SWINFT Supercharger kit by R's RRP

We have upgraded ROM data for Swift Sport with a long data programming and developing which already reputed in Japanese market. There are many changes for this time’s upgrades and the followings are main changes you would like to know about RRP Super ROM ECU. We aimed the engine blow in high rev but also with much torque in city ride. We utilized the accumulated experiences and running data for few years.

1. Mapping data changes for fuel map and fuel acceleration map

Our mapping data of Air-Fuel ratio used to be very weak (thin) to obtain the power before, but we felt that the total torque from low rev to high rev was little less power due to A/F ratio.
This time, we have changed the mapping data especially for pulling the torque using fuel acceleration map well with lower the A/F ratio in fixed driving speed but increasing the fuel when speed up.
This mapping data was modulated for fixed speed driving and also acceleration driving both.

2. Mapping data changes for Ignition map and ignition intake temperature
　 adjust map

The ignition map of Swift is very multilateral and editing the balance of mapping is very important. There are 11 faces mapping data for ignition control.

Basic ignition timing maps are 4 faces and the other VVT-I mapping depends on different angle is 7 faces. VVT-I will read the mapping data depending on the changes from 0 degree to 60 degree. We have changed the mapping each data face very carefully. They say that a car runs fast if the ignition timing is faster but we had confirmed the data by Dynopack machine and found that the delicate map setting is required to avoid the torque down.

RRP Super ROM ECU Version 2 map setting pursuits the easy control your car with smooth torque curve and balanced setting like high power in high rev with advanced angle.

The ignition intake temperature adjusting is to retard the ignition timing extremely when the temperature goes up and also to control the retarding the ignition timing with minus 5 degree in the different condition preventing to less torque when full opening throttle driving.

3. Mapping data changes for throttle open angle adjust map

The former version ROM setting used to be to aim the best response of acceleration but version 2 is for targeting the linear feeling and easy control smooth feeling as same as a wire throttle.
We know type 1 Swift and type 2 Swift has a different character in throttle mapping so we had made the different throttle mapping data for type 1 Swift and type 2 Swift with delicate adjusting.

In the stock setting of Swift Sport, the acceleration response setting is different setting in high rev and low rev.  The same step volume of axel but different rev makes the change of throttle open angle and we believe you might feel something strange when driving, so version 2 has modified this point.

【OE ECU】

Volume of step axel	10%	30%	50%	80%	100%
2000rpm	5%	20%	45%	80%	100%
5000rpm	15%	40%	60%	80%	100%

【RRP Super ROM ECU ver.2】

Volume of step axel	10%	30%	50%	80%	100%
2000rpm	10%	30%	50%	80%	100%
5000rpm	10%	30%	50%	80%	100%

Version 2 targets the linear feeling and easy control smooth feeling as same as a wire throttle.

4. Mapping data changes Valuable Valve Timing map

This is not popular among Swift users but there are 3 types of VVT-I mapping data.

1) Half throttle                    (opening angle 6% to 80% )         VVT-I map
2) Full throttle                    (more than 80%)                              VVT-I map
3) idling                               (less than 5%)                                  VVI-I map

The basic mapping data is (1) half throttle VVT-I map and (2) full throttle VVT-I mapping required to adjust the setting to perform better. Regarding to ver.2 mapping upgrade, we had tested our demo Swift Sport for not only full throttle but also fixed speed and full throttle from 5th gear 1,500rpm.
VVT-I map is the only mapping data to pulls the engine torque changes and required the sensitive setting for map. We have aimed the power and flat torque when full axel mapping. Half throttle is the most important mapping data which we had tested Swift Sport in many different situation like step axel slowly or step suddenly to the floor and could set the mapping data with good feeling of torque even in extreme load conditions.

5. REV limiter

For type 1 Swift Sport : fuel cut limiter 7,600rpm to 8,000rpm
You can choose any limiter rpm.

For type 2 Swift Sport : fuel cut limiter is set in 8,000rpm and also we had set the throttle limiter with 7,800rpm.
To reduce the engine load, basically we had set the throttle limiter in 7,800rpm and also the fuel cut limiter is used for fuel safe purpose.

6. VVT-I work temperature

We have changed the mapping data of temperature setting to correspond for low temperature thermostat.

7. Electric Fan relay temperature

You don’t need to add the parts later. RRP Super ROM ECU can map the fan control too.

	OE stock condition (AC off condition)	After re-map the data
Without driving force	lower than 97 degree
Low driving force	ON at 97.5 degree and at 95 degree stop	On at 92 degree and at 88 degree stop
Low to High driving force	ON at 102.5 degree	ON at 98 degree
High to Low driving force	Changes at 100 degree	Changes at 95 degree

8. Idling change with option

In option, you can change the idling rpm for high camshaft tuned car to stable the idling.
The following is an example of idle setting. We can change it as your request.

[stock idling]
Air condition OFF             : 700rpm
Air condition ON               : 800rpm

[after re-map the data]
Air condition OFF             : 850rpm
Air condition ON               : 950rpm

9. Control the data on descend rpm

During the axel off, we program the data not to descend the rpm in sudden so that you can get the feeling as same as wire type of axel.

We prepare 2 types of setting which are for street drive and for circuit drive. Please notify us when you place an order which you like.
The difference between for street drive and for circuit drive is the throttle map data. For street drive setting, we regarded the easy control and drive and for circuit drive setting, we regarded the response of engine setting. If there’s any appoint for setting, we recommend the street drive setting.
