Hi need stagea 260rs ecu pin outs couldnt find on the manual could you help thanks

Glad you sent this got me thinking about cambelts and all sorts 😂 so i guess everything is fine but still no cold start high idle arggghh only thing left to do now is compare data from an actual r34 gtt turbo and compare there must be something i must have missed out 🙈 hope its not ome of these posts where there is no result 😂

What would cause this?

🙈🙈🙈 dont have a clue with timing, any suggestions?

IMG_0277.mov O2 bouncing lean and rich

IMG_0274.mov IMG_0275.mov Finally got datascan attached are pictures from data

Good point, as i had to re wire the knock sensor plugs, not sure if i switched them while wiring left on right and right in left. Timing will check and get onto datascan. Thank you guys 😎

😂 cant give up now will update, waiting on diagnostic cable so can check values also

Hi guys mights have found something, started engine when cold removed the plug for the gearbox speed sensor, knock sensor neutral sensor, idle went up higher which is what i need. possible chance car doesnt think its in neutral? will have to dig deeper

Yes coolant is flowing, have bleed from both screws one on thermostat and one on idle control. Coolant is flowing smooth without any air. There is no blockage as used air line and water was instantly coming out of all pipes. This is a tricky one 🙈

Hi yes fully cleaned, will remove today again and clean, have noticed when setting idle learn when i connect the tps plug revs increase ever so slightly, will be checking neutral switch to pin 39 on ecu to ensure this is wired

Hi alot of trouble shooting later, repaced the dump valve back to standard idles better no cutting off, still no cold start, changed iacv, coilpacks, theottle body, iat sensor, as inahve two sets of everything still no change. now i may think it is ecu related as the ecu installed into r34 is from a neo stage 4wd rb25det but it is auto my car is manual from factory. Thanks for the reply guys dont know how to reapons individually yet 🙈 attached is picture of ecu

sorry guys dont know how to respond to comments on here thanks for the wiring diagram, im confused as i have r34 gtt here with fuel resistor so i assumed i would need it for this car also. it seems to be working just fine just want to be on safe side. Just need to sort this cold start issue out need it to idle high and then come down once warm

🙈 do the r34 gtt does not have any fuel resistors in place for the injectors? When i google that image it comes back with injector resistor

This is the resistor found in engine bay that Iam askin about

Unplugging iacv doesnt do anything no change

Hi there is power to idle control valve, issue is no cold start, it starts at 900rpm and will stay there. changed idle control with another same issue injector resistor is found on gtt models and stagea. Gt four non existent, with this car now turbo would it need this wiring in

Hi, was wondering if anyone can help with my issue would be much appreciated. r34 gt4 4wd non turbo originally installed stagea 2.5 turbo 4wd engine into r34 got it running just fine with some niggly issues few questions idles at 900rpm cold or hot, ideally when cold should idle high and then drop. It sits consistently no missfire or cut off. Power to idle control valve is present, tps set correctly, diagnostics code 55 no faults. No engine light also. currently using stagea turbo ecu would that cause a conflict? injector resistor, not installed is this important? Will it need to be installed? 4wd light is on also , front abs sensors need replacing as they broke and are not on vehicle hence abs light is also on. Thank you in advance any support would really appreciate.

Hi yes correct , have both 😎

Hi did you ever finish this?

Hi thanks for the reply, doing a conversion to r34, thought maybe would get it up and running on current setup might be easier then replace with aftermarket. As this engine has single turbo conversion, 800cc injectors, hks pro v ecu linked into standard ecu. Has no airflow meters, The standard ecu got water damaged. based on above tuning parts thinking would be easier to source ecu plug in and start, or would i be better to get aftermarket ecu and teach the above mods, sorry not sure on aftermarket ecu 🙈

Currently done this project converted to rb25det, in gt four. Really easy. now in the process of converting the other gt4 into rb26 what s headache 😂 actually stuck on wiring as it is from 260rs stagea the loom and ecu Both were r34 2.5 na manual coupe

Hi picture attached of part number

Based in The UK require this ecu any for sale?
