Megasquirt for my KLZE

[zzzoomx3]

so im thinking i should just do an EMS for my KLZE swap and was looking at this system - http://www.diyautotune.com/catalog/mega ... p-171.html" onclick="window.open(this.href);return false; - anyone have any experience with it?

MS is used allllll the time with ZE's. Especially boosted ones. Check probetalk there is a huge following there for MS users.

[zzzoomx3]

unfortunately - for whatever reason - i cant join probetalk - i keep getting an error saying my email address is banned - no matter what email address i use, no matter what computer i use - ive already talked to the admins about it and they couldnt help me or figure out the problem. so i'm talking to a MS reseller now - and they asked me the following questions - i was hoping someone here could answer them:

"Now this one may take a bit of examining your engine. US market KL
series motors have a variety of sensors the ECU uses to set timing.
There is typically one or more sensors in the distributor and sometimes
a sensor on the flywheel. Each one is triggered by a trigger wheel with
a certain number of slots or teeth, which I'll call trigger points. I
will need to know the following things about your sensors: Where it is
located, how many wires come out of it (what type of sensor would be
even better, but I can usually figure it out from the wires), and how
many trigger points are on the wheel it reads."

Well it depends on what you wanna do, if you are gonna go with a 36-1 wheel then you are gonna be using coilpacks. You can still use the stock disty and run fuel/spark/timing on any MS unit. The newere V3 units are a great system with alot of flexability for tuning. I am waiting for my MSII v2.2 so I can start playing around with that, but I am only going to run fuel/spark on it, not to interested in coil packs right now.

Do some research even on mx6.com that will help.

As for PT, maybe your IP is being blocked, try a different computer?

[zzzoomx3]

i have tried 4 different computers from 4 different places. - who knows - anyway - you lost me with this whole 36-1 wheel thing - and so did he, thats why i posted the question - i guess i should have been more specific in that regard. as for coilpacks - i dont even know what that is - so, i doubt i will wanna mess with it. i am keeping the motor stock for now, maybe a turbo in the distant future. so i guess i just want to mess around with the fuel, spark, air and whatever else i can without having to change any of the stock components, like the distributor and such..

[solo_ryder]

Ok, well in a case like that your best off running a kl31/36 ecu or a chipped K8 and when you go boost do MS, research it till then cause its no walk in the park

[zzzoomx3]

i wanna have more control over my engine than just a chipped ecu.

[solo_ryder]

Well with a ZE and a chipped ECU you aint gonna get much better tuning then that unless you do some decent motor mods and then do a full standalone with MS (that includes doing coilpacks, EDIS etc). Its better to do some basic N/A mods like chip, intake, exhaust maybe cams and maybe also some mild porting to the heads and intake manifold. Other then MS you may be thinking a SAFC or something like, but its a waste of money and will not really help/work on a KL motor.

If you go the boost route then you can unlock some good power with MS, actually I recommend that. If you went with a FPR/FMU combo not only are you going to run pig rich, the setup wont be very reliable. All in all, if you are just sticking with a KL then go with a straight neck motor and get a chipped ECU. MS will not help all that much on a basic ZE motor that is not boosted unless you do some crazy motor mods.

[zzzoomx3]

i already have my curved neck ZE installed - in fact im taking it back out and 'upgrading' a few things. ive already got the exhaust taken care of - headers, custom 2.5" exhaust (no cat), intake and other things are coming, like underdrive pulley, fuel regulator, test pipe converter and decals (joke). i was just hoping to get some feedback on what this guy who is 'building' this MS for me was asking. i dont see it as a waste of money as the motor will always be 'played' with in some sense and i dont wanna have to worry about getting an MS when i do get a turbo.

[marcdh]

anyone any thoughts how much deleting the VAF for MAP style sensor would help in his case? i.e. klze NA, high flowing exhaust system, decent intake.

[solo_ryder]

It would help abit, you can get a solid idle and better A/F ratios from using MSnS.

To answer your question zzzoomx3 - I have heard of that site before so its not a bad idea to buy from them, however, considering the mods I think you wanna do, go with a basic setup that doesnt have a coilpack/EDIS feature. That will save you some cash and it is probably something you wont need but it will have the fuel/spark feature that people want for the most part. You also dont need dual tables unless you are planning on running nitrous or race fuel etc..

Also, consider a v3 board because they built abit better with some surge protection just incase you wire something wrong A v2.2 is still a good unit though. Dont forget to buy the wiring harness!

[zzzoomx3]

thanks for the info - this is what the guy at DIY came back to me with (more money than i wanted to spend, so im trying to figure you what i really need and dont need):

Right now we would have to build a system that requires a little bit of
wire splicing to install. Our full plug-and-play systems take a lot of
development work and at the moment we do not have a plug and play system
for an MX-3. We haven't ruled out building one in the future but we have
a couple other projects that would need to be completed first.

The best option would be to use the K8 distributor's NE1 signal for the
Megasquirt's RPM / engine position input. We can then build a
Megasquirt-II V3.57 that will control all the options you're looking for
- fuel, idle air control, ignition, and you can use its stepper control
circuit for two general purpose on/off outputs for fans or whatnot
(there's no stepper on a KLZE).

Here's a full system quote for you.

MS2357-C $430 Assembled Megasquirt-II with V3.57 PCB
MOD_2357-IGBT1: Single Ignition Output through IGBT (VB921) $20
MOD_x357-12vIn: 12v Pullup on the Ignition Input $12
JimStim-C $95 Assembled JimStim diagnostic board
StimPower $7.50 Power supply for JimStim
MSHarness $65 12' wiring harness
IATwPiggy $22.25 IAT Sensor
38NPT-Bung_S $8 Bung for mounting IAT sensor (steel weld on, or JB-Weld on)
TuneCable $5.50 6' DB9 tuning cable
USB-2920 $20 (Only needed if your laptop doesn’t have a true DB9 port)
Subtotal without wideband-- $685.25

The wideband oxygen sensor is a very useful tuning tool. Almost all dyno
shops have wideband sensor systems they can install temporarily when
tuning your car on the dyno. If you plan on tuning the engine yourself,
it will be very helpful to have a wideband of your own. Megasquirt works
with most popular aftermarket wideband oxygen sensor controllers. We
carry the Innovate Motorsports line. You can find pictures of the gauges
on our website.


Wideband Options—

LC-1 without gauge $199 (you can still view real-time AFR and datalog
AFR through your laptop)
LC-1 with Westach analog gauge $258
LC-1 with DB digital gauge $289
LC-1 with G2 or G3 analog gauge $289
LC-1 with XD-16 digital gauge $399

Wow that alot of cash, you should wait for the next probetalk group buy and go that route. Ask the guy at DIY if there is a OBDI probe harness that can use.

[zzzoomx3]

would i even NEED what he is suggesting? their complete systems are around 400$ - and i know alot of other guys have installed MS on their ZE's and i doubt they paid this much....

[solo_ryder]

Yea, I am not really technically inclided to answer that as I have not even installed MS myself, but from what I know you can save a load of cash doing a group buy or PMing Shoadome on PT, he can help you for sure
