Hi all,

Im getting a Tomei Trax 2 way fitted this week. But i have been told if you change the cam angle you can make it a 1.5 way. Anybody done this?

Reading some info on these diffs it seems they were designed for drifters. Has anyone had one of these diffs installed? Are they very harsh to live with?

honestly, you just get used to it... and pretty quickly....

i have a weldy in my ke70 and i dont even notice it :)

i have a 1.5 way in the r33 and that's the way to go for a car that isn't dedicated drift imho

I'm not sure if you can change the cam angle in the tomei (i was under the impression that it is a fixed), however the lower the angle cam will result in mild locking characteristics, also it will reduce the chattering characteristic of L.S.D.s, reducing unexpected motion changes and increasing stability, allowing it to be used enjoyably on the street.

Nismo lsd GT lsd are all 55 degree cam angle apart from the PRO TT which uses a 45 Cam angle

Advantages of the 45° Cam Angle

A 55° drive-side cam angle in vehicles with reinforced bodies can result in the inner tire moving in a minus direction during cornering, creating drag which can result in reduced times. By reducing the lock ratio by decreasing the drive-side cam angle to 45°, tire drag during cornering is reduced and circuit times are improved. A lowered cam angle also decreases the power to each plates, providing more stable initial torque.

NISMO's Suggested Users

1. Circuit users

* Tuned cars with reinforced rear areas

* Tuning shops time trial demo cars

2. Street users

* Those who want an L.S.D. that is moderately effective on both winding roads and on the circuit

* Those who want to use an L.S.D. in street driving but dislike the chattering

So in short if you can reduce the cam angle it will still be a 2way but be more street friendly

I'd be much more worried about putting 390rwkw down than what happens when you back off! lol

seriously though 2 ways are fine on the street... you have to be a complete muppet to spin it on lift off... if you jump on the anchors and have lots of steering lock on it will step out but very controllable

Diff is in. Feels pretty good. Terry was able to make it a 1.5 way (near enough)

Bed it in for about 15mins as instructed, but ill give it another go later just for piece of mind that it is done properly.

Terry and the boys at Award did a perfect job and their customer service is second to none. Ended up costing cheaper than quoted which was a nice surprise.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
