A few updates

I fitted the fuel pressure sensor on the return line, after the regulator. This is the completely wrong place to put it! I need to move this to the feed line, I switched to using traditional fuel equation for the time being and can now run boost :D

The mayo was just condensation from sitting for a long time so no need to panic there.

The cars getting used a lot despite loads of wee jobs left to do in terms of tidying up. Road tuning is pretty hard with traffic and my limited free time so I've not completed the mapping yet. Need to set aside a full day and borrow a mate to finish this. May hire a dyno depending on free cash.

And I got these delivered the other day

Got the car booked in to get the new wheels fitted and got an alignment (it badly needed the camber sorted) and decided to get corner weighting done at the same time as it wasn't much extra.

Total car weight is 957kg which isn't too bad. The car handles much better now as you can imagine, no longer feels like it handles turning one way better than the other. Really impressed.

How it's sitting now, really happy with how the wheels look.

Did you manage to get the Tacho to work in the end?

Not had the time to look at it again. My next step was to run my own wiring from the ECU to the plug at the clocks as at the moment i'm using the original wiring but i've either wired into the wrong place or its not suitable for the low current.

Got a list the size of my arm of things to sort before I get to that.

Just read your Thread.
Looks really nice.

I have a Question tho.
How did u connect the TPS? 
Do you got any pictures of it? 

Would help me out alot.

Cheers

Cheers man.

I don't have any pictures of mine but I did get the idea myself from Phil's build

http://www.ukstarletowners.com/topic/71206-ep82-gt-ccm-demo-take-2/?page=6

Wiring wise I followed the Link G4+ help files.

It's quite easy to fit, the glanza throttle body has 2 holes where you need to tap threads in to mount the skyline TPS. I had to cut a bit off the pole part you mount the TPS to but other people used washers to space the TPS away from the throttle body

Its very simple to do, bypass the resistor which sits on the IG- circuit of the cluster. Set the duty to drive it in the Link and you can have key on swoop etc too.

Ive done it a couple of times and never had an issue.

Think my issue is I've wired it into a plug near the ECU which I tested with a multimeter and appeared to go to the correct pin on the clocks but I'm going to wire directly to the clock when I have time, this is a low priority.

So I've got some dyno time booked in less than a month to map this myself on an actual dyno which will make life much easier than trying to do it on the road. I'll actually be able to map the ignition tables properly as well as I'll be able to see the torque changing in real time. The guy who owns the dyno has happily agreed to help me listen for knock using my Link Knockblock as I'm not 100% confident my ears are up to the task.

Also got this little lot to replace the wax stat. Got the Toyota gasket, Ford Mondeo Idle Control Valve and gasket and plug and pins to suit. Just need to scan the gaskets and create a cad file for an aluminium adapter

Ah ok yes, that will be your problem, you need to wire it directly to the clocks as they are feed from the Coil, then bypass the resistor. When you get the clocks out its quite easy to see/do.

Finally got the car mapped. Shout out to Chris at Dyna Tune for holding my hand while I mapped it myself. Big thanks to Stu on here as well for all his help getting me started with a base map and all the advice!

So it made 138 hp at the hubs on low boost 0.7 bar and 184 hp at the hubs at 1.2 bar. Pretty happy with that. Works out around 211 at the crank so it's no slouch!

Going to just enjoy the car for a while now. Sort the tacho as well as I'm repeatedly hitting the limiter haha

Overdue update. Car is still going strong, it sat off the road for about 14 months with lockdown, got it back on the road earlier this year and fixed a load of wee issues.

  • Horn wasn't working so got a replacement airbag squib for £11 off eBay. Top tip the same part is fitted to 94-00 Rav4 so can be had quite cheap.
  • Windscreen washers were blocked and couldn't unblock them so fitted Yaris washers with the fan spray pattern 85381-52300
  • Fitted rivnuts for the front bumper brackets for easier removal/fitting
  • Fixed a coolant leak
  • Fitted Bosch 550cc EV14 injectors

Things to do:

  • Service
  • Replace turbo oil feed line which is leaking
  • Replace broken door handle
  • Wire up tacho
  • Got a Radium DMR fuel pressure regulator coming so I will finally be able to tune the car with the modelled fuel equation 

Here is the car as its stands now

I'll be pulling out the wiring loom to modify and add some new wires for fitting this...

this looks like a really well thought out build. good work.

can i asky why did you go down the route of the mondeo ICV? did you have idle control issues?

Thanks, yeah my wax stat is on its way out. Cutting out once up to temp dropping the clutch at lights or needing the throttle opened on hot starts to keep it from stalling. I've set up idle ignition control in the Link ECU which has helped for now but got a prototype for the adapter coming in the next few weeks.

I'm collecting a load of parts for the Fury, most of it is here but still waiting on some bits

  • Bosch donut knock sensor - #0261231006
  • AMP Connector B and pins
  • USCAR injector plugs so I can replace the denso > USCAR adapters
  • Spec55 and Spec44 wire
  • Heat shrink
  • VEMS VR to HALL speed sensor divider - this is necessary for using the ABS sensors for speed as the Link G4+ Fury can't handle the high tooth count over a certain speed.
  • LSU 4.9 connector to wire directly in, will be selling the Link CAN Lambda shortly

e8d44c04dd90bf65fc540ca5280ddb12.jpg

Out comes the Atom, not 100% happy with the ignition and injector fused relays here, it works but could have been much tidier. I fitted the Fury into this gutted standard ECU and it took up the whole space so I've tucked these up next to the airbag for now.

4dcc8e87bee1b96e11a15d2fb9251d0d.jpg

Got a speed sensor for the gearbox, it's a Brantz BR3. 4 pulses per revolution, hopefully it provides a decent speed input to compare against a rear undriven wheel. I stupidly removed my from ABS sensors and loom when fitting the Link as I removed the ABS for the car a long time ago. Should have kept it in hindsight.

Swapping over to the Fury was really simple just load the same map from the Atom and change the temp inputs to have a 1k Ohm pull up resistor (this is hardwired on the Atom but configurable on Fury) and in my case move the CAN wires from connector A to B as the pinout is slightly different for connector A on both ECU's. I will remove the can wires once I get the wideband wired directly.

After I fitted the Fury this happened...

So I had wired it correctly years ago using a spare ignition output but perhaps that output on the Atom can't support the tacho, not sure, ah well got a working tacho now.

My noisy clutch release bearing is properly fucked now. Makes a massive screeching sound when I engage the clutch and it's not so happy about selecting gears!

I'm just trying to figure out what to do here is some background to my issues:

  • I got a LSD gearbox back in 2013 but have no idea if its a plate LSD was just told its a TRD one
  • I also fitted a second hand TRD clutch at the same time (probably should have just fitted a new one)
  • The garage I used didn't tell me to fit a new clutch release bearing, I've since learned this is best practice when fitting a clutch. It's been a bit noisy since fitting in 2013 but wasn't going to pay to have the box off again at the time.
  • I asked opie oils which oil to use and they recommended Fuchs Titan Race Syn 5 which says on the Fuchs website its not suitable for synchromesh gearboxes haha! Not ideal.
  • The gearbox has never been as smooth as the one I removed and it's occasionally crunched into 2nd or 3rd when driving the car hard. This could be an issue with the release bearing, clutch, syncros, the oil etc... 
  • A good few years of crunching when changing the gears has me worried about the condition of the gearbox now or how long it will last.

I have my original gearbox stored in my parents garage... stupidly without any oil or anything plugging up the driveshaft holes. It's been sat there since 2013 so I'm going to need to open the box and see if it's been damaged with rust from moisture entering it.

I think I'm going to remove the LSD gearbox on the car, open that up and inspect the LSD and generally see how it look inside. That way I will know what oil I need and if it's worth just repairing any damage.

I'm then going to open my original box which has sat in the garage and if by magic its rust free I'm going to order the seal kit and all new bearings and have it reconditioned and the LSD fitted. If it's rusty then I'll probably have to scrap it which is a real shame.

Then I'll fit a new Exedy Organic stage 1 clutch at the same time.

I know what your issue could be with the box. My gearbox started going noisy which i put down to clutch release bearing. Upon removal the centre spline on the trd clutch had worn loose so that got replaced with an excedy stage 1. Bearing was fine but new bearing fitted along with a new clutch and the noise was still there. It was some of the shaft bearings in the gearbox in the end. 
 

New bearings in the gearbox and the noise completely went. Not only that the gearbox now feels the best its ever felt. Engagement is perfect and the difference really was night and day.

TRD diff in my gearbox also and think its just harsher on the bearings over time prematurely wearing them out.

Ah cheers for the reply! Yeah when the box is off and open I'll be replacing all the bearings anyway for piece of mind.

I think the clutch release bearing looks quite rusty anyway having a look at the original image I got sent back in 2013.

Thinking the plan is to get both gearboxes rebuilt with all new bearings and synchros (if necessary). That is of course if the sorted box is worth saving. I hope it is, will open it up and have a look over the next month or so.

Getting the internals super polish finished has so many great benafits + my starlet box is really very quite after polishing. I'm very impressed with it. 

After alot of research I'm using Volvo hgv gear oil. It's extremely durable. Does not seem to be affected by temps (great cold as well as hot), as well as extremely long long life. 100k oil changes. 

transmission oil SAE80W-90, 97305 sorry a mistake with the part number as pointed out by claymore, The oil I used was sae50 part number to come soon.

Who did you use for superfinishing?

 

Nice updates on the ECU side too @Patches 👍

I am quite fortunate my place of work does alot. There not accessible to the general public. 

If you search around there are more and more companies doing it. Also you can get ceramic beeds your self it's not a complex process. 

We have always called it ceramic bead polishing/hardening it's been around for awhile now.

Just make sure you get the right oil classification for the box. Some of the results for SAE80W-90, 97305 show equivalent oils as GL-1 which isn't suitable. Is it suitable for LSD boxes? I know that helical and plate types differ.

I've always had good results from Redline products in non-lsd gearboxes if it helps.

Trevstar has had his gears superfinished, might be able to help.

Yeh sorry it was a sae50 (good spot thanks). The oil put up was an equiverlant oil for the volvo shift gearbox. A quick search on the gearbox At2612d which is my reference. let me dig out the part number in my documents.  

Sorry patch about the compents on the build thread.
