SMT-6 gains !!!
Hi everyone,
I will let the dynos speak for themselves...
All SAE corrected
The green is with SMT timing advance and 13.5 A/F
The red is with SMT timing advance and stock A/F
the blue is with stock timing and stock A/F
Ignore the high rpm clutter on those runs its partly the SMT's fault and the fact the engine was heat soaked to hell at that point (Dyno was recording over 94 degree temps in the garage). So this shows that A/F doesn't do much for my car, most of the gains are from timing. Next up is gonna be race fuel and a **** load more timing via SMT-7.
This was the best run of the day with +8 timing advance and 13.5 A/F and no heat soaking, Also with the DEK working right.
Much to my surprise no detonation at all, so there's alot more timing advance to be had with lower air temps and race gas , but best of all the VQ35s with 4th gen ECU swaps can get even more.
201 WHP and 197 WTQ and Im still making power at the stock redline, I need an extended rev limiter...

It's a piggyback so you can adjust it as opposed to the JWT or TS which is just set values.
Those are great gains, and more importantly, clear, concise dyno proof of the gains rather than the typical, anecdotal "Well it feels pretty awesome." Numbers > Opinions. 12hp is definately a gain you can feel. That's about what a Ypipe gives and it definately kicks you in the pants a little more.
Hater comment - You need to raise your MEVI switchover by about 400-500 rpm and a 7200rpm limiter.

you can tune your own A/F
you can tune your own Timing
you can adjust for larger/smaller injectors
you can add extra fuel injectors and write maps for them
you have a rpm switch for the DEK (SMT-7 has 3 switchable outputs)
dual mapping, you can run two different maps and switch or have a mode for nitrous
maf to map conversions (next project this winter)
closed loop lamda tuning (you can tune A/F in closed loop, good for boosted guys or for cars that run lean in closed loop from having no EGR)
thats the big list theres alot more things its capable of
Disadvantages-
no rev limit increase
no speed limiter removal
hard to install, not for the novice tuner. If its not done right it can operate quite terribly.
SMT-7 is where its at, I wouldn't recomend anyone buy the SMT-6. Just wait for me to get the SMT-7 up and running later on this year.

Yeah im gonna adjust my DEK switchover to a higher setting, I left it at 4800 to be consistant on the dyno... Also I need a higher rev limit, I will wait until TS gets the 96 5 spd limiter cracked and go with a L spec ECU setup.

This is awesome. How much more could I advance my timing since I have a VQ35? How much of a gain do you think A/F and timing advance combined would give with a VQ35 (I run 94 Octane all the time, so as much as it can be advanced)? I have the stock 95 Ecu.

A/F depends on how rich the car is when you initally dyno it, mine wasnt to bad so I didnt make much of a gain there. None the less I wrote two A/F maps 13.0 and 13.5. The 13.0 is for road course and daily drive, the 13.5 is for 1/4 mile use only. This will eventially be my race gas program with the SMT-7, I will run + 12~15 timing. Funny thing is with a 13.5 A/F it only gains 2 WHP and a little more TQ.

oh and SMT-6

I am totally in the dark about this product. Did a quick google search and found some info. Any one car to fill me in a bit. So this unit could be easily used to tune a FI car with larger injectors? What about using a Z32 MAF? Price? Just direct me to some links if you don't want to anwser.

Never tested until I bought product, soon after I got Joe to buy it. Joe got it working before me. You can tune for bigger injectors. No need for Z32 maf, once we get it all working, we can switch to a MAP sensor.

I think some of you guys are confused as to what this is. It's a piggyback controller that can alter injector and ignition maps (among other things)... it does the same thing that they do with your JWT or TS ecu (except raise the rev limiter). It does the same thing that Emanage does, it does the same thing for air fuel (but not for ignition timing) that an S-AFC does. It's just a brand of product we haven't seen used until now. The good thing about it is that you can alter the stuff yourself (or have a shop do it) as opposed to relying on JWT or TS to set the values (which are then unalterable unless you send your ECU back to them, etc).
This isn't some magic modification that anyone can slap on their car and gain 12hp and tq. If you've already got an aftermarket ECU, there's no point. If you've already got an S-AFC, it won't do anything for your air fuel that you can't do with the S-AFC but you could adjust timing with it. It does the same things emanage does, same thing other piggybacks do, you guys just haven't heard of this brand and product most likely so that's why you are like "wow what is this and why haven't I heard of it this thing seems awesome?" It's just yet another good option for tuning.
98SEBlackMax please don't think I am posting this to in any way belittle your gains or your efforts here. Making a new piggyback work on a car like ours that doesn't have a ton of aftermarket support is no small feat. I just wanted to clear it up for some people perhaps think this is some never-before-heard-of event, the adjustment of AF and ignition via piggyback.

I'm going to have to dissagree with you on that one. In my experience it seems that aftermarket ECUs are only relivant for the things which you cannot do via a piggyback. Such as increased speed and rev limiters. Unless of course you've had the luxury of having the ECU company actually tune your car in person. This is specifically the reason why I chose to go with the L-spec TS ecu and keep my SAFC2 to do my own A/F tweaks.

joe can you e-mail me a copy of run_file 28? I wanna compare it to my best dyno

You know what I meant. I should have qualified that statement. If you have something like a normal JWT ECU or TS ECU (not L-spec) that already adjusts the air fuel and ignition timing, then there's really no point to something like this. Sure you might be able to get another 2 or 3 hp, something like that, by fine tuning things further. My point was that this doesn't do anything that can't be done with another piggyback or ECU, and I think you and most people knew that. My post was directed to those that think this is some magic device that will give super gains over and above what they already have done, which if they've already adjusted their AF and ign timing, is not the case.

That's what, 20-25whp with the A/F tuning (headers and all of my other mods most likely threw it off somewhat).That's almost too good to be true. Poor tranny.

Also IIRC no one with a 4th gen has been able to directly advance timing with E-manage or any other piggyback, just retard timing. Also when you compare E-manage to the SMT-7 the SMT is far superior, its just not as user friendly or popular in this country.
Well im gonna get ready and head out to Maxus now, I will see some of you guys in a few days.

I have a JWT ECU but i will be getting a SMT because like joe said a 3.5 can push way more timing than what JWT has on his ECU's.
And what kevlo said is another thing the smt makes your maf obsolete.I will switch to map and prob run ITB's
