hi, i have an r33 with a microtech LT-8 ecu. i recently purchased a MT 2 line handset, plugged it in and handset is informing me that there are 2 errors. There is nobody in my area that can help me as they arnt familair with the microtech ecus.

1:

WAT AIR HOM REF

ERROR CHK 1

2:

MAP RPM TPS BATT

ERROR CHK 2

*im hoping someone is familiar with microtech ecus and can tell me what these errors mean.

cheers 4drftn

I don't know about the 2 line handset (I have the 4 line) but the one that has the error should have the 'ERR' message below it.

i.e.,

WAT AIR HOM REF

Err OK OK OK

MAP RPM TPS BATT

OK OK Err OK

for instance.

im unsure, im sure it said error, anyway microtech tech guy sent me a message back sayin-

You need to go to each of those screens & watch the screen.It will flash every 2 seconds with the name of the sensor & then will flash either "OK" or "Err" next to each sensorYou can download the ECU manual here (link went here)

i viewed the manual but from what i read i think its best for me to find someone that has had experience with ECU's...

Any workshop that fits microtechs should be nice enough to at least diagnose what the Error message is on your handset.

It sounds like the 2 line handsets flash up the Sensor, and then 2 secs later flash up either OK, or Err messages. As it says, you need to watch the screen, first for the type of sensor, and then watch where the Err message appears. otherwise, go visit a shop.

    • Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 馃槄
    • BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 馃珷    
    • I've tried all different combinations of BOVs/ no BOV and stock bypass valves over the years, on gear changes the stock bypass valve seems to get the car back on boost quicker because in part the turbos wheel speed isn't being slowed down by reversion, although they have issues holding boost much over the stock setting. Most aftermarket BOVs you can adjust the spring, tighter will make it open later and close sooner, but in my experience it'll cause a bit of flutter at low load/rpm anyway. I've also got some input into this whole no bov causing turbo wear, never had an issue on any on my turbos HOWEVER, I got my R33 GTST with 200k kms on it, with from what I can see still has the original turbo, no lateral shaft play but has about 4-5mm of play in and out which to me seems like a worn thrust bearing from years (100-150k kms?) of turbo flutter running no bov, so maybe there is some truth to it in the long run. But that'll never stop me loving the Stutututu while I have the car.   OP just wants to know if he can run a atmo vented BOV with no major issues and the answer is YES, plenty of people do it, there's no harm in installing it and seeing how it runs before spending $$$ on an aftermarket ecu, last time I bought a Nistune it was $2400 for install and a tune , unsure of todays prices but you get me. Crazy money to spend just to fix the minor inconvenience of stalling that can be overcome by letting the revs come down to near idle before putting the clutch in or a little bit of throttle to avoid it. You're better off leaving the ecu and tune for after a bigger turbo/injectors have been installed to take full advantage of the tune and get your moneys worth.   Let OP have his Whoosh sound without trying to break his bank haha
    • I see you missed the rest of the conversation where they have benefits, but nothing to do with avoiding breaking turbos, which is what the aftermarket BOV made all the fan boys, tuners, and modders believe was the only purpose for them...
    • But they do so for the other reasons to have a compressor bypass. It's in the name.
