SMT-6 installed!

Talk EMS and Computer related performance

Postby ChrisD » Mon Dec 13, 2004 12:47 am

Hey Kevin,

I got it used for $250 + shipping from Weasy2k. He's a dealer for them. http://www.sea2skytuning.com (all his prices are in Canadian $)

The SMT7 allows you to get rid of the AFM too. People say you can do that with the SMT6 but it is much harder. I think Johnny (weasy2k) said there might be a group buy on the SMT7 after he gets through with testing it?

This is likely a lot easier to tune than the VPC, since you get to alter maps on a laptop instead of knobs like on the VPC. So far I'm really enjoying it. I am currently waiting on a set of o-rings for my injectors, and my wide band to arrive, then I should be ready for some real tuning. :)

I will absolutely keep people updated as I make progress! If you have any other questions Kevin just ask. :)

This is the only site I can find on using hte SMT6 to replace the AFM with a MAP. http://www.idaautomotive.com/changing_o ... ap_sen.htm

Johnny are there any other sites out there that describe this process?

Not that i know of chris, i just discovered that site today as well after talking to Canspeed to find out where my smt7 is :P (delayed :( )
However i was sent a email on how to do it by one of the PP techs, im going to make it into a write up as soon as i get the smt7 installed in my truck and the smt6 installed in car (testing both vehicles).

Maybe I should have read, just saw a dollar sign and was like damn 710! Thank god its canadian... much more appealing.

There is a used smt6 on ebay for 250, dont know if i should do that and try to do the map sensor conversion or just save for the turbo.

The MAP conversion with the smt6 is not a easy job since you have to read voltage of the map sensor for each cell in the smt6 and record voltage of your AFM as well. At this pointyou will remove the AFM and plug in numbers to match your stock AFM's voltage. Then from there you will be able to tune like normal, easier said then done.
If you wait for the smt7 which is about 100-150usd more then the smt6 you will be able to have alot more features like boost control (with boost solnooid needed) and auto tune afm to map conversion :)

Yea sorrya bout the USD prices...im going to be adding them in shortly as well. There is alot that has to be added.

Looks like its around 600 bucks USD, then I would probably need to buy a VPC harness or something since I really dont want to splice all those wires into my harness. Good deal though, when I have extra cash, I will be picking one up myself. I gotta get rid of that damn AFM again. :shoots:

Woud you be interested in a harness? I am in the works of getting harnesses that will plug and play into the 3s-gte ecu's. cost around 100ish usd.

The smt6 is 583usd

SMT6 Analog global settings

Postby 3sgte4me » Tue Dec 21, 2004 1:54 am

Hello,

Does anyone know how to set the analog global setting for fuel? It is perplexing me.

How do you set the fuel settings?

Postby 3sgte4me » Tue Dec 21, 2004 4:50 am

How do you know what to set the voltages to ? ie 4.2 or 3.2 or 5 or ??

you kno wby the type of maf/afm....in our case our mafs read 0v at full fuel (so your upper fuel limit is 0 ) while your lower limit is 5v.
This is because our cars have reversed (for some reason) polarity air flow sensors.

Now what that does is make the smt6/7 NOT go above or below those set voltages because it will set a fault in your ecu if your modification takes you beyond those limits (the stock ecu does not know what 5.5v is as an example)

E6X

Postby Green » Wed Mar 16, 2005 10:58 pm

Jhull's problem sounds very much like the problem im having. I have a Haltech E6X and the signal does seem weak, rather than buy the MSD I bought haltechs equivilant an RA8 or reluctor adaptor, which does the same as the msd in that it converts the analogue synware to a more flat digital waveform. Theres me thinking it would solve my problems............
nope, rpm signal still fluctuates on occasion. Here is a post I made on the Haltech forum:http://p210.ezboard.com/fhaltechdiscussionforumfrm1.showMessage?topicID=1092.topic

Anyone got any suggestions?? Its difficult now as the peeps on the board are starting to slag each others products off and its not really helping my problem!

Not yet. After I get my car set up and tuned with a wide band, the next step is to convert to MAP using the SMT6. This allows me a great deal of extra adjustability. Here are my very initial readings from the AFM and MAP sensor from my greddy boost gauge.


AFM signal --- MAP signal

2.8 V --- 1.0 V (idle)
___ V --- 1.9 V (0 psi)
___ V --- 2.6 V (0.5 kg/cm2)
___ V --- 2.7 V (0.6 kg/cm2)
~0 V --- 3.7 V (1.3 kg/cm2)
~0 V --- 4.6 V (2.0kg/cm2)

Update on the SMT6

Postby 3sgte4me » Sun Apr 10, 2005 6:44 am

Hey Chris,

There are probably multiple posts asksing for your advice but this one is asking for an update on the smt6 setup.

How is it going and are you happy with it or considering going with something else?
