MicroSquirt or MicroTech MT-2, that is the Question!!!!! PING: MATT & TONY!!!!

[1BADASSBUSA]

I know you guys LOVE the MicroSquirt and I am becoming a believer, but I want it too be spelt out for me.  I want to know why the MicroSquirt would be superior to the MicroTech MT-2 for use as a Piggyback ECU, used to run 4 secondary High Impedance Injectors?  I want the Piggyback to be tuned via RPM & BOOST (primarily, I know the MS can use more factors).

Please answer the following questions:

1.  Why is the MiroSquirt better than the MicroTech MT-2 for this application?

2.  What sensors need to be used on MicroSquirt to make it work in this application?

3.  What tuning benefits will I see over the MicroTech, with the MicroSquirt?

4.  Any reason I may not be thinking, but is a reason to use MicroSquirt over MicroTech?


Anyone can jump on the, but I really want to hear from Matt from DIY and TONY.


Thanks in Advance!!! 





PLEASE DON'T BRING UP STAND-ALONE or IGNITION CONTROL.  I just care about running 4 High Imp. Injectors based on RPM and BOOST...

Well i have never used the MT stuff so this would be biased on my part because im more familiar with the MS stuff but one thing that comes to mind is data logging for under 100.00,fantastic data logging software ,  and a great forum with tons of people using and improving it.

That said im sure the MT would work just fine as the uS would work just fine also.

Im not sure how the MT software works but isnt the fuel maps x/y hard coded (meaning you cant change the MAP/RPM scale)?

Sensors all you would need would be IAT and MAP the rest is optional and not totally needed.

Matt would be better to answer some of the more specific uS questions than me but those are a few of the things off the top of my head.

not sure if this is the same but the Megasquirt adjusts the fueling for the altitude you are at and the MT does not that i recall

I was interested in this also???

I am going with a MicroSquirt on my Custom "Ultra" kit from NLR, these questions are about a 2004 Sunfire I am going to turbo for my brother.  Just in case you're wondering the BUSA will still be getting a MicroSquirt...  Going to make a complete 350HP kit with intercooler and secondary injection for under $2,500.00 is my goal....

Yes if you use a second map sensor you can have real time baro correction be it 2.5 bar or 4bar. I believe if your running a 2.5 bar as a primary you have to run a 2.5 bar for the correction and for the 4bar you have to use another 4bar if you buy the 4bar from DIY it comes with the second 4bar already.

I will be using the MS sensor and getting it from DYI!!!!      As well as the MicroSquirt!!!!  Do you guys take PayPal???

You guys? You mean DIY or me?

I actually just placed my order for the MicroSquirt, 4-Bar sensor, CLT & IAT sensors and a couple other things.  PINKY paid for it    Thanks Chris!!!!!

[Gsxturbo]

He's good like that.LOL

I will have your adapter done tomorrow but as fast as DIY's shipping is you will probably get  you uS before this adapter comes in.LOL

When I am hooking the MicroSquirt I buy in the summer (not the one I just bought) to my brothers Sunfire, can I still ask questions on this board?

[Gsxturbo]

Why yes you can ask anything you want about the MS it should work the same on the sunfire as on the busa so ask away.

This was a requirement for MS-I. However, with MS-II and Microsquirt, the sensors don't have to match.

I'm not very familiar with MicroTech myself, so I can't field some of the questions. But I can answer this one:

What sensors need to be used on MicroSquirt to make it work in this application?

At a minimum, a tach input and a MAP sensor. Ideally, you'd want coolant temperature, intake air temperature, throttle position, and a wideband oxygen sensor with a controller. A second MAP sensor for altitude correction is optional.

Will hooking the MS (& Datalogger) up to the factory TPS sensor mess up the factory computer?  Too many things feeding off the same signal, I have heard this can hurt performance?!?!?!?

In my experience piggy backing the MS on the TPS causes problems it works fine setting there revving it but as soon as you try to ride it it starts acting funny i tried resistors to help but it didnt. 

 For a piggyback setup you dont need the TPS at all unless you wanted to datalog the TPS signal as the stock ECU will do all the accel enrichments.

That's what I thought, thanks....

Im going to ship your adapter out in the morning for the coolant sensor.

COOL!!!!! 

I will be ordering a GT35r this week!!!!!!  You know a nice mellow Turbo for the street!!!!!

[Gsxturbo]

Hey Joey if you gave me your address i lost it i have looked all over me computer and i cant find it soooooooo send me your address so i can send this out.

NO RUSH my friend........

You guys are putting out too much good info..Got me confused Tony I'll have to call you again to plan my set-up....I think the MS will still be the way to go but now i see MSII..what the hell Just keep it coming...I like info

LOL MSII is the main processor the secondaries i buld come with the MSI processor as it will do just fine for use with the secondaries with tons of extras that dont even get used so it works fine now in a standalone i think the MSII would probably be better than the MSI as it has more computing power than the MSI does.

Sure give me a call whenever your ready and i will get you setup.

[Matt Cramer]

The Microsquirt is MS-II based, as well, although it loses a few of the MS-II's capabilities (for example, it won't drive four low impedance injectors) and gains a few new ones (odd-fire V-twin ignition control, for example).

[1BADASSBUSA]

All I need is for it to control 4 high imp. injectors for use as secondary injection and I will be golden!!!!!
