I've just test fitted one of these ECU's and wanted to give my impressions. The search feature has revealed a number of heated discussions on the ecu going back to the beginning of the decade - some rate it others don't - some argue that you need all Spoon parts to maximise the benefits including cooling mods, Spoon header, N1 exhaust etc.
My mods are a 4.77 FD, AEM intake, Buddyclub 4-2-1 manifold and a 70mm single exit exhaust and decat. I ran a VAFC2 with a Mase tune and VTEC lowered to 5800 rpms, so I guess my comparison for the ECU is stock, VAFC2 and the Spoon ECU.
I haven't had the chance to drive the car much as the fiddling with immobiliser knackered my battery, but I had the chance to drive the car to get a feel for the performance of the ecu. I'm impressed
The main difference i noted is the increased torque low down and the car pulls hard to redline. No dyno figures but it feels much quicker than stock and the VAFC2. It quietened the exhaust - no mean feat in itself - and it idles like stock. Even though the immobiliser green key is disabled the car still has a functioning immobilser - don't ask me how
I won't be bothering with cooling mods as I don't see the need. I also struggled to find any information on the specific map used for the ECU - so no idea what mods the ECU was mapped with, just conjecture.
For the money and performance gains this is the most cost effective route to take for bolt ons IMO. The Spoon, Mugen, J's and Amuse are pnp and give the boost you need for simple bolt ons.
- AEM is just too expensive to buy and map.£/bhp is high for NA application.
- EMU is expensive and there are very few competent mappers out there and it will be expensive to map.
- VAFC2 is good and Mase only charges £100 to map, but it is rendered useless once you add a 70mm exhaust/decat. Perfect for minor mods
I'll give more impressions of the ECU once I get the car up and running.
