Microtech EMS

[TurfBurn]

The ECU knows what timing it wants the car to have. It sends the signal to the coils to fire, the MPI get's that signal before it goes to the coils, then changes the signal to do what it (the MPI) wants to do. So it will change the timing the ECU sends out, so that is how you advance or retard. So where do you get the alter a signal to fire before it get's it? It goes....ECU-->MPI-->Motor. So the MPI gets all signals, it's wired to get, from teh ECU and changes them before they go to the motor. I guess that wasn't the last post.

The problem with that logic though is the signal isn't to the MPI by the time it would need to send it to advance the timing... That was what Dave was pointing out, and what I was confused on. But I saw blk's post and that's good enough for me... it's a little f**ked up that it can do it... but I'm guessing it is a neat little latent software trick.. and the MPI trails the ECU on timing changes by one firing.

total off last question and sorry if this was addressed but have you wired larger injectors to the mircotech? any problems?

 

[TurfBurn]

I am running 550 cc primaries... so no, no problems.. car runs fabulous. It can take ANY injector... and then on top of that you can wire the injectors together (like multiples in a runner etc) as it can drive down to 1 ohm of load... and it can also handle high impedance injectors... and low and high at the same time... LOL... so no, injectors are no issue.

Thinking about things when I am a good bit more awake, I understand the issue that Nick is pointing out. So I will have to scope the Microtech to see what it does. I realize that it takes 2 full revolutions of the crank to fire all 4 cylinders, and thus Nick's point is how do you know which TDC you are at... is the cam lined up for cylinder 2 or cylinder 3 on that TDC... so I follow that and will have to investigate it further to know... but I'll post what it does or doesn't do. I know it does make a difference when you switch from Batch to Sequential fire on the unit... so the question is what is it doing!

Later!

Any updates?

 

[TurfBurn]

Sorry, not as of yet. I have a race on Sunday so I'm concentrated on prepping the car for that. It'll probably be sometime next week that I'll have a chance to look at that. I do intend to do so though!

 

[TurfBurn]

I'm hoping to check this out Friday night.. not looking forward to having to cut into all those wires to get the values... but oh well.. I offered!

In other news.. I tested the turnaround times on modification/repairs/etc with Microtech... ends up being about 2 weeks total with all shipping to get a unit turned around. So good or bad depending on how you look at it...

Woooooooohooooooo!!! I'm up and running with the Microtech! As of right now I am in the process of breaking in my motor but will start tuning for power once the motor is done. I have a lot of my off boost maps tuned but I'm having a wierd problem with my wideband that is slowing up my tuning. It works and then it shuts off. But not all the time. Go figure. Well I will be posting up update as I progress.

Any news on this?

 

[TurfBurn]

Any news on this?

On the priority list, just not tackled. I'm also trying to figure out a test plan. Is the CAM Sensor a Hall Effect, or is it a magnetic switch? i'm going to wire that so that I can take readings off of it at the same time that I log the injectors... I'll be able to read the cam sensor and 3 injectors all at the same time which should give us the data needed. I'm curious if one time I run it the injectors will all be pefectly in phase by "luck" and another time they'll be out of phase etc... so that's why I'll want to make sure i read that cam sensor to verify. I am very curious about it myself...


And for those wondering on Dave's car... Dave just got his motor back a couple weeks ago. There were a couple little faults we needed worked out. Once we corrected that car started and ran perfect immediately. Dave has been tuning things here and there and making great progress. I'm also running a newly modified ECU so I can test some of those items, and Keola was running before, and should be back up with his new built block in a month or so once the rest of his parts finally make it in from Mental Addiction.

So all told there are a number of us going, and a few australians being added as we speak too! Here come the Microtech's.... I actually believe we may outnumber the Haltech's on the forum in the near future.

Later!

That would be pretty cool to have more units out there so we can see how they work. Maybe you can make sure people post honestly about the issues it may have and also how great it work. Some of the other systems have some "non spoken" issues that don't get talked about.

 

[TurfBurn]

That's the one thing I certainly promise. you'll know our issues. Part of why I'll be happy to publish the sequential information.. good or bad.. as Nick as requested. The package i have to offer is honesty and a fair price. The units are good, they do a great job. They lack some features compared to other units (no closed loop is an example), they have some better features (expandability options, stock sensors, reliability, cost), and they have different overall value. So it's up to customers to choose which thing they want.

The "problems" will be filtered through me for the most part though (although I certainly can't and won't control customers) just so that all the info is in place. I arguably know the most about Microtech's in Protege's and the ins and outs... so there will be a lot more accuracy to my posts about "issues" than someone who says "well my car runs crappy, and the Microtech always leans out when I start accelerating" (which is just a made up thing.... if your pump map is not adjusted you will lean briefly during acceleration... it's a value that AEM, Haltech, and Microtech all have in common).

i can honestly say that there were a few "issues" with the microtech when i first put it into my stock (headers, exhaust, intake) car... it ran pretty bad for the first couple of times, but this was because i was the guinea pig. once we talked it over with steve (turfburn) and got the problems fixed (problems were start up and leaning out issues), the car ran better than stock! no bulls***, i cant wait to get the motor back in and start some real boosting... i know dave has been boosting 3psi here and there and it feels better than 6psi on a fmu... i cant wait to start hitting some real psi, then we will see how it really works!

im sure by the time the microtech is bought more frequently here the issues will be solved, and it will be almost 100% "install and drive"... steve was always there to help me with the issues, even with the 6 hour difference from hawaii to booney land where he lives...

AND remember you were running without a wideband, and no timing light was used to check where you were sitting at for timing trim. Between that and it being the first ever 220cc injector map I had tried to work out it took a bit to nail things down.... but that's why we have been building the base maps like we have...

Dave and Keola have seen probably every "issue" that could come up because they were the first "true" installations because my car is so custom it isn't funny. But as Dave figured out, once the settings and wiring are corrected and to spec, the current base maps work great and the car starts/runs fabulous.

soooooo.. you mentioned they're $1200 due to conversion... Microtech is Canadian, no? I remember reading about them somewhere else a long time ago, but now that I'm boosting, I'll actually have to start reading up on all the EMS's and what they're good for

 

[Bigg Tim]

Tuning issues are a given and a system should not be bashed because some people aren't as good at tuning it as others. It will be nice to have all the info on a system instead of having the "hush hush" problems that no one wants to talk about. I like the way you talk about your unit and others, you don't make it a competition, and it shouldn't be one. Keep up the good work and lets see some numbers/times too!(thumb)

Microtech is Australian... but becaue I have to purchase it and do wire transfers through NSN that is one conversion... and then it will convert up one more time for you.... but 1200 is the U.S. cost on it... the australian and Canadian dollar are pretty close cost wise.

I'd be doing more in numbers/times if it weren't for all the tranny concerns... I'm finishing my mic/listening system right now for my car and then timing will get finished out. Once that is done i'll put up some 10 and 13 psi numbers with the Microtech on 93 octane pump gas. Should be about 2 weeks... the car is sick fast... if my Gtech is to be believed I'm at about 200 horse at 6-7 psi. . I passed an NA protege5 that was doing 90 mph by simply pulling out from behind him, hitting it... and pushing into 120-130 mph.

 

[Lil Freek]

yeah.. 1AUD is like 0.95CAD

S'all good, though - I'm still just learning about EMS and all that jazz... I'm going with EIC for now, and I'll just keep trolling around and reading up for the summer.
