Apparently car runs rich from factory, bit more power to squeeze out of it if I can lean of the a/f ratio a bit

Stock Power run done close to when I first got the car for reference:

Hey mate, just wondering if you had the 180km/h limit when you did the dyno run as you have not mentioned an a/m ecu, if yes what gear was the run done??? cheers

By the speed, 3rd automatic.

4th gear will be in the limiter.

Nitto h-beam connecting rods
Nitto crank collar
Nitto high compression custom pistons
ACL Race bearings - mains / connecting rods
ACL Race ProSeal engine gasket kit
Brian crower 1mm oversize valves
Ross metal jacket balancer with cam / crank trigger kit
N1 water pump
Nismo low temp thermostat
Oil restrictors

Camtech RB26 camshafts
Camtech valve springs and titanium retainer kit

Genuine Nissan front / rear seals, idler and tensioner
Custom Gates belt

IGN-1A race coils

Dyno sheet - Mild Tune (will push it a bit later when its proven to be all well)
Engine torque is that divided by the diff ratio. 3.7 in this case
Annnd its on a hub Dyno hence the power curve "interuptions", if it was on a roller it would be smooth as silk.

Hello, I have a 1998 R34 coupe and im having some weird problems.

The other week i got in to drive it and when i unlocked it problems started,

1. The tacho and speedo dont work,
2. The bell chime for door didnt chime,
3. The interior light stays on,
4. The passenger door wont lock with the button on the remote or drivers side panel.

It still starts and drives fine,
I disconnected the battery and reset the ECU which worked, but then it happened again and again now that trick only works sometimes.

Any ideas thanks
