Hello to Sau looking some info regarding Y34 Rb25DET, I have wired Adaptronic 420D on my car, I know this ecus are quite old but i had it in my garage maybe last 4 or 5 years, and now i dare and start the car, system is old but still engine runs perfect and smooth, But... there is questions regarding gearbox, first what i didnot liked that i had to cut 1 and 120 degrees wires to CAS, after this tacho is not responding on dash, and second i have no slip and 4wd light on, i drive car today and gearbox works fine anyway it changes gears smooth as before (i didn't tried it yet with aggressive drive condition) Does anyone uses any type of similar ecus like piggyback? and if there is possibility to change gearbox with manual and fix and have 4WD in working condition?

Hi guys, looking for opinion if that worth to swap vq30det instead vq25det? i couldn't find any topic with similar project, i wonder if awd system will work properly and gearbox will fit straight? idea is that solving issue with ecu tuning as vq30det is supported by nistune, actually some will ask why change the engine instead of buying ecu? but first i couldn't find any ecu for that and second i have spare vq30det engine already)

I took my car to dyno today, car is bone stock no modification at all and showed 187 AWHP is that normal results? i know this post was maybe asked here for 10K times but still how much is average results with ecu tune, intercooler+exhaust mods?

Noted, Thanks

U mean big intercooler, exhaust and intake ? few question, in tiptronic between changing the gears hitting few time rpm is ok? and how much should stock boost ? my is about one bar is that normal ?

Hard way Thanks how much normally good condition vq25 shows on dyno ?i mean whp ???

Thanks for reply, Actually car is bone stock for the moment, i know both ecus and even more represented adaptronic in my region, but looking budget option like on stock ecu or even emenage which i can do easily but still looking for some light mods, also i wanted to check the car on dyno but DD we have only rear wheel drive and does stagea supports to have full torque on rear maybe fuse remove or something like this? more details for stock ecu rom tunes?

Hi guys long time not posted here on SAU, so i have to registered as new member, so any update for ecu solution for vq25det? i have one of ultimate under my hand and i understand that is budget upgrade for the ecu but how good does it works? also any plugin wiring available for ultimate and vq25
