Yo, just hoping to get some opinions/advice about the microtech ecu's on RB20/25 engines (especially the LTX12 series) as it seems hard to get any info here in NZ & i see a lot of the Aussie guys are running them.

If you are running one what are your thoughts on it? what are they like at driving big injectors (550cc on an RB20) do they have closed loop & does it equal the factory's system? are they easy to tune?

& i heard the LTX12 can be purchased with an adaptor loom to plug into an R32 RB20DET loom, does anyone know if this is true?

Cheers, appreciate all your feedback. good or bad

I wouldnt say  "a lot fo aussie guys"

I only know of one person with a sky using a microtech

What does your tuner over there prefer?

Hmm i thought the 2 most common ecu's for skylines in OZ were Microtech & power FC?

Tuner is trying to sway me to just get the standard ecu chipped but i am possibly looking at adding other things later on so an aftermarket management system is looking like the only option. & the only two that are in my price range are Microtech LTX12 & power FC but i have had an extremly hard time trying to get hold of the RB20 type so it is almost out of the question.\

Your thoughts on the microtech?

Microtech's are built to a price they do fuel and timing and thats about it. The LTX12 has a few extra options idle control and an addtional output its all on the website I think. You only need to take a look at timing control in a static conditon to apprciate how shit the timing control is. As for idle control actually not to bad considering. Closed loop - kiss that good bye.

The biggest problem is the variation of MAP signal - you can use a pill to damp this off but in the end its still shit. I am bias because the main aim of where I work is tuning standard ECU's but we also tune microtech, xede, PFC, haltech , motec and autronic. You will actually gain more torque across the board with the standard ECU as it has better timing control. ie the standard ECU is 1deg sensitive as is PFC whereas a microtech is about 3deg sensitive. You just cant go past the PFC or Chip IMO. (Hmmm prepare for the flamming)

If your tuner wants to go with a chip go down that road and get it retune later chances are there wont be that much to do.

Microtech is ok, im running one in mine (LT8) it does just enough of what i need, albeit no Cold start IAA etc... but still starts fine.

if i had my way again and had the cash i would definatelly go with a PFC, enough said....

nothing wrong with a Dribbletech.

they all have pretty good resolution with the 3dtuning software. and they can be configured to read all of the factory sensors.

im not sur about closed loop.

at the end of the day it comes down to how well its tuned. fullstop.

    • Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!
    • Curious to see how the SpeedTek stuff holds up
    • The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...
    • Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.  
    • I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
