microtech are not as bad as everyone says. its just harder to get working on a rb. very easy to tune but very hard to wire into a rb. alot of people use the plug and play adaptor for rb25s hard wire it in properly and its fine a bit of a hastle to wire in but once done its worth it.

like i said before if the microtech was not given to me i would have gone a nistune or PFC

The model number implies its drivers, normally halved.

An LT12 can do 12 cylinders batch fire or 6 sequential.

Correct me if I'm wrong anyone..

I know its meant to be sequential but the last LTX12 I scoped definately wasn't sequential - that was using a 36-1 inductive trigger and factory inductive cam trigger on a 2/1JZ. Apparently microtech's cant use too higher tooth counts and which means on an RB they are most likely only using the 6-5-4-3-2-1 signal not both the 6-5-4-3-2-1 and 360 tooth signal like the factory/PFC do.

Hence why there is very few ECU's that I trust to use the OEM RB CAS for stable igntion control.

i've had microtech's on a few cars now, I think they serve their purpose, cheap to tune & simple, very broad in load points for tuning, best suited for drag cars and rotors. but if u don't mind turning the key a few times on cold days & warming it up for 5 mins then microtech will be just fine

if you don't ever plan to pass a emissions test, and you don't care about the microtech's timing drifts and you can be bothered with aftermarket aux's then go for it.

its just not the right way of doing things.

How well do they work as a piggy back?

I've an auto & I'm looking at a possible high flow turbo in the near future (nothing major, only aiming for about 220 - 230rwkw) & I'm a bit stuck on ECU choice.

Since no stand along aftermarket ECU works properly with a R33 auto (as far as I know from reading old threads), & some old suggestions was running a combo of SAFC + STIC, however the latter is nimpossiblebile to find. The other one was to run a Emanage Ultimate, but I found most tuners around my area dislike them for some reason, so no point getting it if I can't get a decent tune out of it.

I talked to my tuner about the issue & he reckons a micro tech wired in piggy back would do fine with a stock high flow.

Any opinions on this?

Can you explain in more detail?

I thought the harsh changes where due to replacing stock ECU which backs off timing before auto changes gear with a stand-alone aftermarket one, which doesn't do that.

But since you retain the stock ECU wouldn't that mean this 'back off timing function' is kept as well?

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
