  1. That looks perfect - thanks for the info Adam!
  2. Hi, we run a ST205 in local tarmac rallies (with plug-in TST205 G4X). It has finally done a head gasket, so we are getting it checked then rebuilt with bigger cams, e-throttle, larger turbo etc. When discussing with our engine builder, he is keen to have individual cylinder EGTs. I'm thinking the easiest way is to connect the thermocouple probes into an amplifier that goes straight to Canbus (something like this maybe: https://www.ptmotorsport.com.au/product/egt-can-expander/). We can then setup protection like in this thread (\\https://forums.linkecu.com/topic/16732-can-tc-egt-safety-2jz/#comment-106946 - many thanks for the info). We will also have a PowerTune dash hanging off the Canbus and I'd just like to check if there is anything I need to be aware of like: - should I put the PowerTune dash on a separate Canbus to the Thermocouple Canbus amplifier (I think the TST205 has more than one canbus?) - any other recommendations for a Thermocouple->Canbus amplifier? Given the electronics involved there are lots of things out there that seem really overpriced given what is inside them. I'm familiar with Canbus, given I have successfully decoded a handful of Canbus IDs on our GR Yaris (we are using the PowerTune dash to log these when racing whilst we wait for our GT4 to come back to life). Any info much appreciated. Regards Peter
  3. Hi Simon, we have a ST205 GT4 Celica currently running on a G4X Extreme Plug-in (part no TST205X). The engine has developed either a crack in the block or a head gasket issue, so we are going to be putting a ST215 engine in. I have looked at all the I/O channels required and either the wire-in Extreme G4X or the plug-in TST205X has more than enough to run the engine plus any extras you might need.
  4. Ok - so with a copy of PCLink for the G4+ open on one screen (with my current map loaded) and a second copy of PCLink for the G4X open on the other, it seems I should click through all of the below config items, expand them, and copy all the config across to the G4X. Is that correct? Is there a quicker way of copying tables across? That looks like it may take forever.
  5. Hi, I've upgraded from a G4+ wire-in to a G4X pnp and noticed that PCLink won't load the old G4+ map. Is there a 'how to' guide or an import tool or something that I can use to copy the appropriate settings across?
  6. Hi - just planning how to connect our Powertune dash to a TST205X we have just started using. According to the G4X Extreme quick start guide, CAN 2 is shared with DI9 and DI10. Given we have a plug-in, I'd prefer not to use CAN 2, as we then couldn't use DI9 & 10 as digital inputs (spare DIs are a bit scarse on a plug-in). According to the TST205X manual, we can use CAN1, but should probably chop off the Grey and Yellow RS-232 wires so they don't accidentally act as an aerial. Is my understanding correct?
  7. Ah yes - thanks! I tried that out, set the teeth to 36/1, and attempted to start. Got backfires, so took 360 off my base timing (ie set it to 78-360=-282) and it fired up. Many thanks
  8. Hi all, we recently got our freshly built 3S-GTE running in our ST185 caged tarmac car. To get it going, we used the two trigger signals from the stock distributor. Now that we have a much smoother idle (thanks Adam), the next step is to switch Trigger 1 to a reluctor CAS with a 36-1 tooth trigger wheel mounted on the crank (for more stable timing). In the Trigger 1 settings I have set 'Multi-tooth post' to 'crank' (was previously 'cam'), and set the Tooth Count to 36 (was previously 24). We have set the reluctor nice and close to the wheel, so we have a good strong signal, but we still seem to be getting Trigger errors. I think it maybe just a matter increasing the Trigger Arming Threshold a bit, but not too sure. I have attached a copy of the tune (fuel=off deliberately), a triggerscope, and a log. Any comments most welcome. 59-Shelley setup for CAS with fuel off and CAS closer - still no luck.pclr 210307-Shelley triggerscope with CAS sensor much closer still 5 errors.llg 210307-Shelley with CAS sensor much closer -full log.llg
  9. I tried it out this morning and it idles way better! Many thanks Adam
  10. Many thanks Adam - I'll give it a go in the next couple of days. Regarding fuelling, the 'master fuel' in our ST205 tune (that I used as a basis for this) was set to 9msec. Given that this engine is running 720cc injectors (compared to the standard 540cc injectors in the ST205), I also reduced 'master fuel' to 6msec in an effort to compensate. I acknowledge this is a bit of a blunt instrument, but the plan is to get it properly tuned soon anyway. Let me know if you think it may be worth bumping that back up to 9msec.
  11. Hi Adam - please find attached (sorry - took me a while to get back to where the car is). It basically started, I had to keep it alive with a few well times stabs at the throttle, and then I let it conk out eventually. Apologies for the IAT being stuck at 50 degrees - it is a wiring error that I fixed after taking the log. Please let me know of any areas I should be looking at. Thanks 210303-Shelley surging idle PC log.llg
  12. Hi all, we recently managed to fire up our new 3s-gte (installed in a ST185 caged tarmac car). The engine is a pretty standard Gen 2 (as installed in ST185s) engine. Standard compression, standard throttle body and air bypass valve but larger cams (272 from memory). To get it started, we took the tune from our other GT4 (a ST205 with a stock engine that had been tuned by one of the local tuners), altered the I/O to match, and got it going. However, the idle seems to surge a fair bit when it is cold to the point where it needs a bit of carefully timed throttle to catch it from stalling. I am no expert in tuning, so I'm not really to sure where to start to get get it to have a stable idle. I have attached the tune file - any pointers on where to look would be welcome. 55-Shelley change to 3bar GM map sensor.pclr
  13. Possibly. When I wired up our 205 originally, I loaded up the Link base map, and it started straight away so I didn't bother checking anything else. We then took it to the tuner, they worked their magic, and we have been running it in events ever since then. I've just loaded up the Link base map, and it shows an Offset of 1 degree. When I got our 205 back from the tuner, it had an offset of -4 degrees (not much different). Given that I had to add 360 degrees to get our new engine to run (with direct spark instead of a distributor), it looks like maybe the base map is out by 360 degrees. I am definitely no expert though!
  14. Many thanks guys - added 360 to base timing and it fired up straight away!! Brilliant
