hay every one,

2 quick quistion is it true if you get a aftermarket computer,pfc/heltec/motec/ems/ect,ect,ectin the r34

do you loose the function with the :Traction Control

I ask cos i got a new ecu put in,then he told that i will loose this function

an also the engin light,the tcs,an the slip lights in the dash permanently stays on

is this right or have i been screwed an he has'nt done it right

also now it takes about 4-7 sec to even start,

were as before it turnd over straight away.an when it does start the frist three sec it sound like its going to stall

after that it goes to 1500 revs until it warms up then drops to 900 revs

does it sound like he has'nt tuned if properly

thanks

did you get a new ecu or just a chip? I got a chip & tune done in my R34, and NOT a problem in the world with TCS or start up. take it to get looked at by a new workshop and a new tune. may make ur car run better & they may find the reason why ur TCS isen't working. and the slip light woulod be shitting me off if it stayed on.

"IF" the ecu has stuffed with the TCS and wont work again, get some wire snips and cut the wire to the Slip light asap. haha

Where'd you get yours chipped if I may ask?

Sounds like a few minor issues. I doubt TCS will work as the stinger doesnt appear to support it. You may have idle issues.

Why dont you ask the shop why it doesnt start up as fast as before and why the lights are always on? If you did then what did they say?

you have to check if the ECU has Plug N play base map on it. If you use chip in your stock ECU or aftermarket with plug N play such as PFC, then the should work fine...

My guess is your car is tuned with ECU which does not have a base map, the ignition delay is caused by poor cold start tune. It is easier to tune while engine is hot and running however cold start is tricky, as by the time the tuner got the approximately right tuning, the engine would have been warm. Then to wait for the car to cool down again takes 2-3 hours, which I highly doupt the tuner will put the car back on the dyno.

This is also consistent with your idling problem, sometimes if the tune is not done properly the car will actually stalls on its own, you got to give it a bit of fuel... you won't have this problem once engine is warm no?

Hmmmmmm, sounds just like the problem I had when I had a Microtech installed. No AFM causes heaps of things to not function as they should. Changed to a PFC with a Z32 AFM and bingo all is good again. Does yours still have the AFM?

it may be that the TCS/ABS computer required signals from the ECU , such as TPS . This is similar to how the auto works .

This means those signals must be replicated by the ecu (which the r34 pfc would do) or you may be able to bridge the sensor outputs required for TCS . this is often how other ecus such as motecs and autronics are installed to work with tricky features like traction control , automatic gearboxes , stability control etc

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

      Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
