Hey Guys,

I had my R34 converted to manual 2 months ago and just purchased an R34 manual ECU to change over. After I swapped the ECU over to the manual one, suddenly the TCS OFF & SLIP lights are showing constantly. I went for a drive and the engine ran fine without issues.

I did a couple of searches and saw suggestions of coil packs needing replacing, but I find it really weird that after I swapped the auto ecu back, the warning lights don't show? Were there any differences between R34 ECU's over the years?

I didn't try to pop a burnout or anything :D

If it is coil packs then the engine light will also come on, so there would be TCS, SLIP and ENGINE.

If it is just the slip and tcs lights you would have to do diagnostics and see what code you get...

From memory the way the data is transferred from the TCS/ABS computer differs with the manual and Auto ECU, so it's throwing up an error due to that. if you can live with the TCS not working I wouldn't worry too much. That's pretty much the only system that is affected, won't change performance in any way.

Thanks man. I'm going to get my car NISTUNE'd so I guess I'll have to decide whether I want to be looking at an A/T light or TCS / SLIP lights instead :)

Just remove the bulbs :( It's the quickest way to solve those errors.

      Rebuilt Rb25det issues

      By KyoyaR33 · Posted

      Howdy all,   I had my rb25det S2 rebuilt and finally started it today but have run into a few issues  Engine sounds like a a diesel easiest way to summarise like small ticking, gets louder when revs are slightly adjusted  The engine builder repainted the engine cover leaving no where for me to go off with lining up the CAS so have it as central as possible so not sure it that could be affecting it?, changed the gearbox fluid too but won’t seem to go into gear when running, and only 1 to 4 when off having a hard time finding 5th and reverse anyone got any ideas or a base for me to start off? much appreciated

      Well, no. It's an 023, which is pretty similar to an 040. Although it is hard to tell from the specs, as given.

      Hmm. Maybe the (other thing I forgot about!) Haltech removes at least some, if not all, of the problem I described. I guess there is still the possibility of getting it wrong if the AC is set up/wired up for the Haltech as if it was in an R34 (simply because it's on a Neo), and that's playing foul with the R32 AC computer.

      Glad it eventually came out Duncan!   I believe that might be 040. 044 is the inline pump, so has screw fittings in and out. 040 is more just drop it in fuel and the bottom is "open" (mesh) from my memory
