MegaSquirt Stand alone? - Page 2

Redstar · 04-16-2009, 06:40 PM

The megasquirt is a good system, but I'm not sure you guys realize how much work you'd be getting into installing a megasquirt system.

DIYAutoTune.com Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products

Browse around the site, read everything you can, they even let you download the software. Crack it open, see if it's really what you want.

It sounds like you guys read too much into that ONE blog article about how a Greddy emanage was blamed for blowing up a lexus - how many engines do you think megasquirt is "responsible" for destroying (or was it user error...)? If you're doing something stupid it doesn't matter if its a piggyback like an SAFC or a $$$ Motec standalone.

Standalone's are awesome, but have you ever used one? Not all of them are very user friendly. I'm not saying don't buy the megasquirt, hydra, AEM, Haltech, ect. I'm saying know why you're buying it.

For what it's worth, I like the emanage blue so far, it's done everything I've asked it too. No it's not perfect, but it fits my current goals for my car.

Most likely the MegaSquirt Stand alone because the MSD retards the timing and youll blow your motor at that psi..thats what i was discussing with someone else a while ago. and bigger injecors than the 315cc from the 7mge your going to need the 7mgte denso's that are 440cc

Redstar · 04-16-2009, 09:11 PM

I don't follow your post, sorry.

The msd btm retards timing under boost, that's usually a good thing, you'll probably end up doing the same thing with the megasquirt - but what does that have to do with psi?

Please also remember that 10psi on a CT26 is not comparable to 10psi on a T3/T4.

Yes, with a T3/T4 you could easily overwork the 315cc injectors. The 7M turbo injectors are low impedance and I think from 1990 on they were side feed. Why not use the drop in (top feed, high impedance) RX-7 denso's that come in the 460cc and 550cc flavors and save yourself some trouble? I don't know the part numbers off the top of my head, but I'm sure they're somewhere on this site.

The megasquirt can do A LOT for you, much more than just retarding timing and adjusting fuel curves. Their site is really pretty good, go check out the software and get an idea of all the features you'll be able to tune with.

That's why you pay to have someone who knows what the hell they're doing tune your car. If you can't afford that and the computer then you can't afford an engine management system.

Buying a piggyback is just as stupid as buying a computer you don't either have the knowledge or money to tune properly.

JMR2 · 05-06-2010, 08:26 PM

does anyone have the ecu pinout for a 91 5s

SW21T · 05-06-2010, 10:22 PM

my 5s ecu plug is not the same as the one ur showing me. i have a [26][16][22].. i have a megasquirt 2 standalone that im planning to install soon. does any have any idea on how to set up the megasquirt like the settings and stuff? right now im running a 3S-GE turbo with a 2nd gen head and a 3rd gen block but im still using my 5s ecu with a msd btm.. just need to know how to setup the basic setting on the megasquirt 2

328FTW · 05-07-2010, 06:03 AM

^ Are you going to running crank trigger ignition? What size injectors? The is more to it than slapping it on. If you want I can give you my map when I'm done tomorrow, it is rough but it is a gen 2 3sge with 360cc injectors and a turbo running direct coil control off of a 36-1 wheel with the sensor mounted at 9 skip teeth.

JMR2 · 05-07-2010, 08:30 AM

im still going to use my distributor and maybe a 370cc injector.. thanks i think im going to need the basee maps so that i can get started..do you have the ecu pinout for a [26][16][22] plug im going to try and make it like a plugNplay

fvillota · 05-07-2010, 10:58 AM

WTH do you have an auto?!
the auto ecu uses that pin out!
here it is..

328FTW · 05-07-2010, 11:00 AM

Lol nvm abouth the picture I can't count

And I'm not sure if you can use a stock dizzy, I can't remember, might need another tooth removed. An edis crank trigger conversion is cake though, I went to direct coil control to cut back on things needed, the megasquirt does near everything except scratch my nose. What kinda turbo you running? Makes a big difference, mine is small for quick spool and at 8psi it makes no where near what a bigger turbo would make at the same psi.

fvillota · 05-07-2010, 11:04 AM

Lmaooo!! i just uploaded and took it down since you had the one up.
hahaha

328FTW · 05-07-2010, 11:06 AM

^ lol owned, If you looked though mine had the wrong count on the last plug.....I think. Don't trust me right now I'm impaired.

fvillota · 05-07-2010, 11:08 AM

yea it did! i was gonna pm you, but just in case i was counting wrong, i took it down. lol
the pin out he is describing in an auto ecu ...
unless there is some other 5s plug i haven't seen yet.

328FTW · 05-07-2010, 11:20 AM

Well we will know when he posts back

Anyway I attached a tune file. It is not really tuned just the car was running and I had the wastegate hooked up for the first time. Needs A LOT of work before I hit the track but if you want to crack it open and have a look and get a feel go ahead.

JMR2 · 05-08-2010, 07:25 AM

thanks for the pinouts

JMR2 · 05-08-2010, 07:47 AM

oh yea my car was auto before i swaped it to M/T. but im still using the auto harness and ECU with the 3S-GE for my daily driver. i had a ct26 but now i have a T3/T4 with a 60A/R..planning to park the car soon so i can install the megasquirt 2 just need to get my other car running first
