Hey,

I should start off by saying that I am looking at maybe getting a V36. I wanted to ask any V36 owners out there, who have been on a dyno how much power you guys are making?

And if any one has done any modifications ( catback exhaust, intake etc) or tuning (UpRev), how much difference did it make?

I apologise in advance if there is already a thread like this, please post a link to the thread if possible

Thankyou

I bought my auto V35 350GT coupe from a specialist importer. Compared to all the others I test drove, mine seems to have a noticeable advantage in acceleration over the others.

The car was auction grade 4, other than a grounding kit, tein coilovers with EDFC and the factory powerduct (with K&N panel filter), the car is stock. There seems to be very touchy throttle response, particularly at low rpm. I cannot find out what could be generating the extra power! The dealer seemed to think it was chipped. I checked behind the passengers side panel, and the ECU is stock. Would there be any other way to see if it is chipped?

A friend seems to think it may even have upgraded cams- apparently this is pretty common in Japan as it gives them a bit more low down power and torque.

By comparison, I drove one (not from the importer, but someone who was selling privately) with a kinetix plenum, stillen induction and performance exhaust, and I think mine would leave it in the dust.

I haven't done a standing 0-100 yet, nor had it dyno tested.

Yeah I did a bit of research into grounding kits, and apparently they do wonders, particularly for autos. The thread I found was for a us website, I think it was g35driver.com

Someone asked if they actually do anything and the responses were all overwhelmingly positive.

Still, great car, ant it'll run rings around my old R34

I'm still yet know a person who has installed a grounding kit and had any impact outside auto shift firmness and placebo.

Placebo is a very powerful thing.. I read many many posts about people claiming Strut tower braces had 'significantly reduced' bodyroll. which a STB cannot possibly do.

Grounding kits work for auto boxes due to the bad factory grounding. It helps shift smoother and abit harder. Another thing I noticed was my audio got a tad louder. The guys down at the audio shop said it was the grounding that made it better. Who knows...As to gaining kW....I doubt it.

I dont think it makes it look messy....then again I made sure I hid the wires where I could...looks pretty much stock.

I wouldn't say its in my head, as I didn't know it had a grounding kit until after I bought it.

But it definitely had a definite power advantage over the others I drove, like I said- is there a way I can tell if it is chipped or has aftermarket cams

I think the general sentament is the difference is not the grounding kit. something else has been done to it.. possibly a throttle controller installed which has changed the throttle body response vs pedal position. Could also have had a uprev tune, which uses the stock ECU.

Grounding kits will normally only help if you factory grounds are very poorly designed, or corroded/damaged. The extra grounding from the transmission casing to the engine/battery may help as the auto solenoids probably ground to the transmission casing, and the existing grounds are a source of voltage drop.

Did it accelerate better at full throttle, or did you just notice the throttle pedal response was different?

    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
    • Does the scanner do all the CUs in the car, or only the ECU?
    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
