Hi all

well i have bought a raptor charger kit and also the car will be intercooled and am wondering about what ecu to run

My question is i have a Unlocked SMT6 which my tuner said they can tune easily and better than my N/A tune (currently is installed in my N/A build the ecu is really just made for boosted cars) do you guys think the SMT6 will run the car as i cant see the point in spending another $1500 or more on ecu that i dont need.

P.S
Im not chasing massive numbers like 175 -185 im aiming for 155-165 wkw and i will be happy with that at the time being lol

He forgot to mention as well that if possible want to have a timing retard system put in if possible, for safety more then anything.

The SMT6 should be able to handle it. From what i remember about the Sprintex kit, the SMT6 monitors post-supercharger intake temps and retards timing if needed. Please correct me if i'm wrong.

Haltech E6X, fully programably aftermarket ecu, can get it for 1300 new.... that is if the STM6 is like 1500....

I love my haltech, customer support is amazing and its aussie company

Thanks Magna00 forgot about that

definately something that you can get tuned, i would most definately go full aftermarket and then use the stock ecu box instead of the fancy pants one you will get with it as a full stand alone ecu means you have to get it tested for emissions etc.

Also as far as im aware the auto 3rd gen ECU aslo plays some role with the gearbox so that makes it worse for a full aftermarket ECU if the car was a manual it wouldn't be a problem with a full aftermarket ECU

Jason, whats your thoughts on the Chiptorque units since you have one?

Are all of the items above or any of them MAP sensed ie built in MAP sensor? Pretty essential for good fuel control under boost

I am pretty sure the SMT6 controls or bends inputs into ECU like the Xede etc, I have been down this road in that past .......... and i don't go down it now.

Get something that intercepts between ECU and injectors for total realibility of info going to injectors and ignition. This is the only way that learning by the ECU will have no effect on fuel and ignition once the car comes on boost.

im 98% sure the SMT6 has a map sensor

Does it have it internal or external, either way its ok just so long it has one.

I didn't see that feature listed when I looked on their website 10 mins ago but I could very well have missed it.

not having a dig BUT

whats the point on spending all this $$ on mods and keeping it auto? Unless of course for some reason your physically unable to drive a manual it would seriously just suck the power out of your car! It also makes it easier to get something like a megasquirt ecu which you can not only adjust fuel and that but also timing etc

Because his Missus cant drive a Manual, if we were dead keen on going big power with this car we would of brought ScreamingTE's car before it had even come onto the market, and would of been going down the route of a forged bottom end.

End of the day it will still be a DAILY DRIVER so reliability needs to be resonable, aka not broken constantly. Also the SMT6 has an external MAP sensor, anyone wants pics i can go outside and pop the bonnet and take some if you so wish. Brad we will need to get hold of the map sensor if you are keeping the SMT6 (and no not the one out of my car :bowrofl: )

Could be a problem

Mmmmmmm let me have a think about it, i might get the part no off mine and see if i can source one through work

This may be a dumb question


Does it have to be one of a SMT6 or any map sensor

Possibly a GM Type 2 Bar would be all you need I reckon, they are about the most universally used MAP sensor in the world :)

I think this man is correct, i remember heathyoung saying something about the something being holden on these and a 20 dollar part.

Ill have a sticky at it tomorrow when i can be bothered getting up

I don't see why you can't use an SMT6, especially if you already have one anyway, and your tuner is experience with them.

Yes, they utilise a MAP sensor (In my case a Haltech unit).

For your application they are fine, they can do dual maps as well, handy if you wanto run a set for water/meth injection later, or wanto run a "safe" map incase you get crap fuel, unusually hot weather etc (you could run a temp sensor to switch maps at a predetermined point like the Sprintex ECU does, if you wanted to)

If it tickles your fancy, you could use out of the outputs to run an injector for water/meth also (in the same way the Sprintex runs the 7th injector).

Glad your happy with your Haltech, but I don't see why the OP would wanto spend the extra money/hassles on one.

Tell me, which of the features of the EX6 is he gonna use that the SMT6 doesn't have? Yep, Most likely none.

I'm guessing EX6 is probably something in the region of $2500-3000 bought, fitted and tuned. And then it will never drive as nicely as the factory ECU + intercepter style ecu (less time consuming to tune also).

Compare that to the cost of fitting and tuning an intercepter-style ecu the OP already has lyeing around ($600-1000 at a guess?). Seems like a no brainer to me.

I will be running a air 2 air intercooler (something different)

so a Haltech map sensor will work on a SMT6 if you dont mind me asking would you be able to get me the part number.

He forgot to mention as well that if possible want to have a timing retard system put in if possible, for safety more then anything.

He probably wouldn't need to do this if he has decent intercooling, as intake temps will vary much less than with the un-intercooled Sprintex setup.

Although if the OP doesn't mind spending the extra money on dyno/tuning time, it couldn't hurt to have a "Safe" set of maps he can switch to, incase he gets a bad batch of fuel etc.

Yeh you can switch between the 2 maps on the SMT6 either when it's set to sense something or you could even put it on a switch to toggle between the 2 maps.

What size/brand/type cooler out of curiousity?

Soirry mate, I can't tell you anything more than "Haltech 2bar MAP sensor". Anyone else have a part number by chance? Otherwise I imagine it shouldn't be too hard to find out from Sprintex, A sprintex dealer, the Aus distributor for PerfectPower, or Haltech themselves?

I'm guessing it would be a universal part, or there would be at most only a few variations on the Haltech MAP sensor.

Its an Air 2 Air intercooler that will have a thermal fan attached to it to push more air through it (when stuck in traffic) the size of the cooler is 450mm x 300mm x 65mm so not to big but big enough there is a photo in my members ride page.

Hey BJ31OS

What size pipe connections does your IC have? 2.5" or 3"? 3" would be ideal but can see how 2.5" works if its that size

im pretty sure is a 3 inch connection

im pretty sure is a 3 inch connection


Why go so large? 2.5 would be enough flow... wouldnt it?

The piping itself will all be 2.5 but the inlet/outlet of the Intercooler is 3inch, for 99 bucks for a brand new Monza one it will do heh.

Its just a standard 2 bar Bosch map sensor - Haltech stock them, but they are available from anyone who gets bosch parts (ie. auto leccie).

They are a 0-5V output, not pulsed - keep this in mind, there are some pulsed maps around.

The holden part is the intake air temp sensor, haltech wanted $40 for it, holden $20.

If you want the bosch part numbers - the 0.2-2.5 bar is what you are after. (0 281 002 119)
