I took a drive down to Artech in Guildford on Friday to have a chat about a Remap on my DC2.....
Met Romain who was very pleasant & took the time to stop what he was doing & sit down/talk through my options over a cuppa..most impressed.
Im pretty set on a eCtune remap now. Its ideal for my needs The ECU will need replacing for a P72 (i think) OBD1 along with an OBD2-OBD1 harness converter. Car will then get fitted with a wideband Lambda & knock sensor.
The eCtune system allows the chip containing fuel/ignition maps to be substituted with a real time emulator connected to a laptop.
As the car is then driven, realtime map info is displayed on the laptop & can be altered as you drive....timing/fuelling/VTEC point etc etc
Once the map has been tweaked on the road, it will be a trip to Surrey Rolling Road for fine tuning on the rollers & definitive before/after plots.
Finally the new map can be written to a chip using an Eprom burner & jobs-a-goodun!
Romain explained that the main achilees heel of the UKDM ECU (compared to JDM) is just how uber-rich (safe) the cars run in VTEC. Pulling fuel out of the map creates more power, especially when this is adjusted to cater for any breathing mods on the engine. A touch more ignition advance may be possible too, though the standard ignition map is pretty good.
After discussing my requirements for a smooth & progressive power delivery, VTEC will be lowered to ~5300rpm to remove any classic VTEC "kick". The eCtune system also allows VTEC to be disabled at part throttle/high RPM configurations. An ideal tool to prevent VTEC when cruising on the motorway for example etc etc
Other UKDM owners who have had ther cars tweaked have ended up with gains across the board...especially mid-range & low down (10BHP+). Peak power gains of 7-10BHP minimum were also achieved.
Shows that a proper ECU map to take into account any physical mods is a great icing on the cake mod & will extract the best from your B-series motor. Well worth considering if you have modified your car.....
On Surrey RR he'd expect to see standard flywheel power around the 170-175 mark (with my bolt-on mods) SRR use a Dyno Dynamics RR which always read "conservatively" to say the least. Romain said stock EK9's tend to produces 165-170fwhp....
When finished, peak power should be up very nicely past 180 with excellent gains in mid range torque/driveability.
I will update the thread as & when i get booked in.....
