s13 megasquirt help needed

[JDmisaac]

I'm very new to the nissan game but i just bought an s13 with a ka24de swap in it and am starting a boost build on it. So i've been doing research on all my ecu options for my ka-t build and decided i wanted to go with a standalone ecu system for many various reasons. i've read the diy autotune and several other forums and how to on the installation but was wondering if anyone has pics of their installation into an s13, also is there anyone on here that specializes in building the systems and can set up a basemap on one for the right price let me know all info you have on this
your help will be greatly appreciated.

thanks

I personally don't know anyone running the Megasquirt system without issues. Better to go with a ROM tune or a proven standalone like the AEM EMS.

[JDmisaac]

yeah idk anyone doing it with a 240
i know some people running megasquirt on miata's and i really like the setup
but just installation on an s13 seems really complicating.

i thought about emance or enthalpy
but if i did that there's no room to grow without completely sending it off and paying to have it reflashed.

[WDRacing]

Stay away from Emance, dude is a real piece of work. Enthalpy is a far better option and if you get a tune for some pretty big injectors then you won't need to worry about growth. Just start out with low boost and turn it up as you feel comfortable. A 72lb program will be good for more then 400whp.

I'm sure you could just ask him what he recommends for your peak power goal and he'll be able to tell you the best combo to buy that will work with one of his rom tunes. I have yet to hear a single complaint about the tune not being good.

the Megasquirt ecu doesn't get along with the KA CAS, I think there's a work around, but honestly I've been around the KA scene for the last 8 years and I don't know anyone that didn't have all kinds of issues getting the MS running even half good. Not the same for all makes/models like you said. I know others who have had great success and you can't beat the price. Just not a good option for the 240SX when we have some really reliable ROM tune options.

Just my opinion bare in mind...others may differ.

Welcome to NICO btw

[JDmisaac]

good stuff
yeah the plug and play obviously seems alot easier.
i'll just have to take some time and think of how i want the setup as far as all options i'd like for it to have like overboost launch control etc... are they able to do all of those to it as well?

and thanks for the welcome
tons of useful info on here.

[WDRacing]

I'm not sure if you can do a launch control...I think maybe you can. EasyE will find his way in here with some better answers. He'll tell you about burning your own chips, which is always a option as well if you want to do your own tuning.

Just thought I would chime in and say that last year I was in the same bucket as you trying to figure out what way to tune my car RELIABLY. I went through Emance, Efi specialists, then I found Enthalpy through Enjuku. I have done a fair amount of business through Enjuku, and Ken Harrison. So I sent them an email. Got ahold of Ken and told him what I wanted to do. Within two days I got an email back from him with a couple questions about how i was gonna run my setup. After answering them, he gave me what he thought was his best option for my setup and power goals. He was very knowledgable when it came to getting my ecu tuned right. With that said I ended up going through Enjuku, cause I was confident in his experience and abilities. I sent my ecu to be tuned, and received it back within 10 days. At this point my setup needed a few minor kinks worked out on my end to be complete, and running how it should. I had a wideband, and a boost gauge. I felt safe so the first thing i did on her maiden run was hammer down. With a steady eye on my boost gauge and wideband. And seeing nothing but perfect readings. I beat it, for probably a good 4 hours. Without a hitch. Took it to the dyno and put down 260hp at 10psi. I was happy. Very happy. The fact that all I had to do was send it out, get it back. Plug it in and go was a huge relief of stress. Not having to hassle with building a board, or buying a complete standalone. Made me feel like I saved my pocket from heaving out large sums of money. And saved my brain from a huge headache. Till this day I have been in contact with Ken for a retune cause I have rebuilt my motor and got a bigger turbo, injectors, etc... His customer service is top notch. And you will find no one better. So you know how i feel about this. Sorry for the long story but, I feel there is only one way to go on this one.

[JDmisaac]

awesome
thanks for the input
yeah i've heard nothing but good about enthalpy
so i'm just gonna scoop one off ebay for 265
that's a steal to be plug and play
and save hassle of standalone and dynotune fees which are outrageous.

that my friend is NOT enthalpy...that is emance, contact Enthalpy thru either his website or thru enjuku.
pretty sure enthalpy is not on ebay... someone else chime in to confirm.

[JDmisaac]

wow
i definitely didn't look into it much
but would have thoroughly before i purchased it
but i just went back and checked
and it definitely is emance

but the titles all say enthalpy for it
wow wonder how many people's been f*** over because of that.

but good call on that
i'll check through the other legit sites

Is megasquirt really that hard to get going? I actually personally know two people running them on their SRs, and that's harder to set up because of the distributorless ignition. I really like the DIY feel of megasquirt, so I thought I'd go for it when I went KA-T, but now I'm not too sure.

[WDRacing]

The SR is easier...

Like I said, I don't know any one running the MS on the 240 with the success of other stand alones or rom tunes.

I run MS on my s14 and it runs almost perfect. The only reason for almost perfect is cause i have yet to take it to a professional tuning place.

[JDmisaac]

is it ka or sr?
if ka do you have pics or more info on your installation
thanks bud.

[Rhapsody]

its ka-t and i have pretty much a writeup on how to do it. And i can also help with tuning and all that stuff. I'v been working with megasquirt for 3 years now so im getting pretty good with it.

[JDmisaac]

good deal man
exactly what i need mine's gonna be ka-t as well
so whatever info and pics you got
send it my way it'll be greatly appreciated.

This is for Megasquirt I PCB 3.0 on a S14

Here is the link to all the pics so you can see em full sized.
http://rides.webshots.com/album/5777824 ... host=rides

First here is the mods on the megasquirt needed to get the s14 cas working correctly. If you have an s13 just follow DIY Auto Tunes guide.


Seconds here is the wiring diagram for splicing the megasquirt into your ecu. All the red X's you see are cuts. This is because if you leave the wires on both megasquirt and stock ecu it will either not work, or you will get bad signal.


Last we have the stock timing map for an S14 KA24DE. Its show in RPM and TP, but can work fine for RPM and MAP.


Also here is the pinout for the s14 ecu for your reference.


On the next post ill upload my tunes. Which is the really good stuff. With what you see here will get you to the point of installing megasquirt but it wont run correctly until you set timing, fuel, etc. etc. etc. so wait for me to get the rest up.

[JDmisaac]

worddd
what all needs to be disregarded for s13
i've got s13 with ka24de in it.

just that first section to get the s14 cas working with megasquirt. Instead follow diy's guide for modding your megasquirt.
http://www.diyautotune.com/tech_article ... _240sx.htm

You can still use my wiring diagram and timing map.
what have you got done so far with your megasquirt?

[JDmisaac]

good deal man i appreciate all the info
and i haven't even bought the megasquirt yet
i'm just workin on my build as of right now
and was looking at my options since nissans are a little
harder than hondas as far as ecu setups for boost and just figured that'd be my best option
for upgrading my build and everything down the road
and also gets rid of the maf setup haha


map for the win

[Rhapsody]

Yeah going the megasquirt route is for thoes who are looking into the furture. Once you understand how it all works you can pretty much install it on any car you want and do anything you want with it. Price wise unless you actually get the kit and build it yourself its just as much to get your stock ecu chipped. A completed MS1v3.0 is around $340, and the MS1v3.0 kit is around $190. You need to know what your doing if you get the kit. I'v built 3 of then before and each one took me around 6-8 hours to complete. Not to steer you away from megasquirt or anything just letting you know its not the easiest way to go.

[JDmisaac]

yeah i feel ya
and i have nothing but time
me and my boy megasquirted his miata so got the general feel of it
just gotta find someone to build my ecu for me
i'm not really trying to mess with all that
not the greatest in the world that solders
so anyone on here want to build the ecu for me and i'll pay you

thanks

[Rhapsody]

just get the already built one from Diyautotune, you can even ask em to do the mods for you for an s13 and anything else you want. Like mod for running electric fans and stuff. I highly recommend both of thoes mods if you don't want to mess with soldering or screwing up your megasquirt. Just talk to matt from sales and he will get whatever you need.

What i recommend is.
MS1 V3.57 (you can always upgrade to ms2 later on if you want.)
mod for s13
mod for running electric fan
innovate lc-1 wideband conrtoller + sensor. (you don't really need a gauge cause you can use the labtop)
tuning cable db-9 to usb (need this to connect labtop to megsquirt.)

[JDmisaac]

wordup
yeah i'm gonna get in touch with him
and find out what he can do as far as a price
for pre assembeled with all my features and s*** i want
and possibly throw me a basemap for tunerstudio.

which tuner do you use on your comp?

[Rhapsody]

Doubt he can give u a base map, and you should read up on the megasquirt manual. What i mainly use to tune is megalogviewer and the tuning software that comes with innovate lc-1 wideband. That timing map I posted is base timing. I can give u my fuel map, but it can only get you started. Its gonna depends on injector size and other stuff. Just send a message my way once u get everything installed cause theres a bunch of stuff you need to do before u ever thing about tuning, like calebrating your sensors to work with megasquirt. Burning msns-e to your megasquirt, etc,etc,etc.

[JDmisaac]

thanks bud i'll definitely be hitting you up
and yeah i'm workin on the injector issue now
trying to get some sti injectors on the cheap
but may wind up going with stock sr's for the beginning
and yeah we got my boys miata setup on ms with lc-1 wideband

[Rhapsody]

i use 460cc rx7 injectors, easy to find at junkyards. all u need is a ebay fuel rail that will fit em. you can send them off to be cleaned and tested so they work properly. cheapest way to get good injectors.

[JDmisaac]

word
so those cheap fuel rails work pretty straight any pics on a setup with one of these?
and how the lines run.

i thought about going top feed and i already have a set of fc injectors off a 13b

good s***.
