Micotech Ecu On Rb Series Engines.

[Drift_Mulisha]

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?

i cant offer anything RE: Microtech.

ive never used one, and wont ever use one

my guy uses PFC all the way.

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.

[R31Nismoid]

i agree.

stocker ECU/PFC you dont need to worry about all the cold start crap and what not.

Already done for ya

Some plugins have timing down to 0.35 degree now.

Stay with standard ECU and remap. Much better than any aftermarket options. More reliable etc.

I would only ever use a microtech if I went back to a rotary.

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.

Microtech doesn't have closed loop (yet).

There is another (unofficial) Microtech website HERE.

the car i got is running a microtech on an RB20, seems to run fine, will let you know more once i've driven it enough (only just bought it)

God knows i'd preffer a motec or something
