ecu's

If i knew it was for an Rb20 & you were going to be tight, then just get a power fc, couple hundred bucks for a 2nd hang one ($500ish) & their virtually plug & play, if you can get hold of an rb20 one (unlikely) then its plug in & away you go, if you get an rb26 one (most likely) then all you need to do is swap inj 4 & 6 pins around as they fire in the wrong order, then cut & bridge the o2 sensor wires & afm wires & your done, all thats needed is an ecu pinout of a 32 gtst & gtr ecu, take a whole of 15 minutes to get it going..I have a proper (easy to read) tutorial if you need it, as at the end of the day, a pfc is the best & easiest ecu for people on a budget, Can tune via the hand controller, very cheap to buy!

i have no question that it would be the easiest way to go being plug n play, and most tuners know them well. its just the price factor. I have never seen any for $500. they are all $800 + 2nd hand

I've never paid more than $500 for a 2nd hand pfc...By the sounds of it, your wanting a heck of a lot for next to nothing

[poeticjustice88]

no not at all. I know the prices that are asked for these types of items. I am simply trying to find the best option for cheap price, arent we all?

i am not trying to find an autronic sm4 for $800, i am simply trying to find the best option available for $800.

I have been searching quite a lot over the past two weeks for these items, and not once have I seen a suitable PFC (rb25,rb26) for less than $900

Oracle, what was the product you were using in one of your vehicles to retain the highest voltage to the injectors or ignition regardless of power draw on your electronics system?

I cant remember what topic you mentioned it in. I just remember you saying regardless of what electronics you turn on, your main function (either coils or injectors) never drop below a certain voltage

[baz]

If its for sale for $900, offer $800 or less?

[poeticjustice88]

lol I know I can always barter, but what I am saying is I have never seen them "advertised" for $500 like you said

[baz]

I've bought x3 pfcs & paid $500 for them all..their out there, bartering is always fun also

[poeticjustice88]

haha, as I said, no trouble with bartering, just have not seen any posted for anywhere near $500 is all

Its a "Buck/Boost DC-DC voltage converter"

I used it to power the injectors when using a Microtech as MT does not have any provisions for injector latency.

I think if you have the skills to assemble an electronics kit, and you are ok with being more involved with the installation / tuning of your ECU, a MegaSquirt is a great option.

I am using a MegaSquirt II (MS2Extra to be technical), and it is quite a decent ECU for the price. I didn't assemble or install the ECU, but then again, I didn't own the car when it was fitted. I would have no hesitation about doing it myself if I had to, it's fairly straightforward.

My friend who assembled and tuned it has a lot of tuning experience, and he prefers the software to MicroTech, EMS, Wolf, and Haltech - it's much easier to log when tuning, and the fuelling is done in a different way, which takes him less time to get right.

It's not necessarily smooth sailing all the way - we've had to sort out several issues. But most of them would have been the same no matter what the aftermarket ECU was (voltage drop in fuel pump wiring and 3 dead fuel pumps).

To install one, all you would need is:

- A MegaSquirt II kit - $278
http://www.diyautotune.com/catalog/mega ... p-119.html
- A wideband sensor and controller
- A USB to Serial Adapter
http://www.diyautotune.com/catalog/usb- ... -p-67.html
- Tuning cable http://www.diyautotune.com/catalog/mega ... -p-35.html
- A pigtail harness to connect to the original loom (or a full harness if you're feeling dedicated)
http://www.diyautotune.com/catalog/18-m ... p-114.html

That's about it. You can fit an intake air temp sensor from a Commodore, and wire up an automatic RB30 TPS for acceleration enrichment, and you're done. All you'd need after all of that is countless hours to assemble, install, fix faults, tune, fix more problems, tune again, fix more problems (and so on, haha).

As I mentioned, it might be a cheap way for someone knowledgeable to get quite a decent ECU and have a go at tuning it themselves, provided you have the patience and time to spend getting it all working.

Or he could just buy like a power fc for like $500 when they come up cheap & his good to go or buy a 2nd hand nistuned ecu etc..Why bother buying an ecu kit then having to assemble it etc etc..

[baz]

btw i think my old boss still has a haltech e11 v2 with a patch loom for like $400

[theS-man88]

The MegaSquirt is a seriously good bang for buck option if you've got some knowledge and are prepared to put in some effort getting it to work. You don't have to buy them as a kit, they just cost more if they're pre-assembled.

If all you want is to be able to edit ignition and fuel tables, change injector constants and other basic stuff, a PowerFC or Nistune will do fine (although the N12 ECU is a bit of an 80's dinosaur). Probably a bit more straightforward than a MegaSquirt. At the end of the day, if you don't want to do a lot of research, and you're going to get someone else to tune it, you're probably best off using whatever your tuner is comfortable with.

However, given the amount of features you get with a MegaSquirt (II and III), their price and the capabilities of the tuning software, I'm surprised that more people on this forum haven't used them.

It's for an rb20,not an e15et
