  1. Thanks Crackerjack - as it turns out, we are also building a ST185, and have done exactly the same thing (stolen the hole left by the Cold Start Injector) and stuck a Bosch open element sensor in it. Unfortunately, we haven't yet got as far as starting it up, so I'm not sure how well it will work in practice. With the 205, there is no cold start injector, and the stock Air Temp Sensor is even further 'into' the manifold, and is a M16 screw-in design (difficult to adapt the Bosch sensor to fit, given its mounting arrangement). I have spoken to our tuner and we will probably weld on a boss on the rear wall of the Intercooler core (right next to the outlet) and stick the sensor there. We will then be able to compare those readings to those of the stock sensor. Have you logged any data from your setup? I'd be interested to see how well the sensor performs there.
  2. I've done some more 'internet research' about the stock IAT sensor on the GT4, and it seems that it is very prone to heat soak and very slow response time. I know its a long shot, but does anyone happen to know of any 'open element' type IAT sensors that will easily fit in the Gen3 3S-GTE? The IAT sensor in these cars is squeezed in just after the throttle body, so it is quite difficult to get at.
  3. Thanks cj - what you say makes perfect sense. I had forgotten about the rapid drop in MAP limit at 110 degrees. I take your point about the IAT readings. The IAT sensor seems to be accurate at ambient temp (always close to ECT when car is cold), but the response time seems way too long. I'll see if we can get it out without too much trouble and have a look at the response time. cheers Peter
  4. We have a Toyota GT4 (model ST205) fitted with a Link G4+ Storm ECU that we use for short course tarmac rallysprint events. The car is largely stock, with just a few upgrades (rebuilt stock turbo with steel wheels), coilovers etc. The car has been tuned in Perth by one of your major dealers who are well experienced with your ECUs. The car has been a lot of fun, weve been chasing an issue where the car feels like the ignition system (which is single coil with a distributor) is 'breaking down' at certain (random) times. To eliminate the ignition system, we replaced the cap, rotor, and gapped the plugs smaller during the last event, but the issue still occurred. We enabled ECU logging during the last event, and at the particular time we felt the issue occurring, I have examined the logfile in detail, and it seems to be the ECU applying a limit to the ignition timing. I have attached the logfile and the ECU tune. I have spoken to our tuner about what may be causing it, but as it is not easy to repeat it is difficult to pin it down. The specific questions I have are: 1. In the logfile, at file time 16:34.46 through 16:37.76 the logged parameter 'Limit Ign Trim' goes from 0 to -2 degrees a number of times. We actually felt this in the car - felt like a misfire of some sort. I've looked at the various limits setup in the tune, and discounted: a) MAP limit. MAP only gets as high as 212kPa. MAP limit is 260kPa, with a Limit Control Range of 15kPa, so nothing should happen until we hit 245kPa b) RPM limit. We are well under the RPM limit c) I don't think it is a trigger error. The Max RPM recorded in ECU Statistics is a 'normal' number Maybe it is a Engine Coolant Temp limit (the ECT is 102/103 degrees at the time)? Looking at the ECT Ign Trim 3D Table, I'd expect some sort of limit (goes from 0 limit @ 100 degrees to -8 limit @ 110 degrees), but I'm not sure why it is so 'sporadic' in the way it is applied? Can you please have a look and advise if this is what you'd expect, or if we need to look at some other settings/logging? Thanks 06-Angelina - enabled ECU logging.pclr 190314-Rallysprint Rnd 5 - run 1 thru 4.llg
  5. Hi Tech Support - it looks like the AEM module now does 10Hz GPS logging out of the box. If you guys could start working on at least being able to capture the data in the ECU for starters that would be really useful. PCLink etc mods could come later, or maybe we could export into another package for display/analysis. Any thoughts?
