ECU options and info

[Guest ugp]

ProEFI 128 ECU seems to get good praise too ; I think the big advatage is it is Flex Fuel Capability

The proefi's are nice unit's I must admit. Finding one over here for reasonable money doesn't happen often though.

 

As for the flex fuel, guess what, the MS3 can do that too

Me personally, I would get the Mapper to select the ECU; if I am ever fortunate enough I would get either RyanG or Dimitri to map her. Not too Sure what ECU Dimitri uses

 

He seems to remap a whole load of Bosch Motronic units for Audis from what I hear, and he's bloody good at it too by all accounts.

A lot of interesting stuff being talked about, however there is one major consideration, who fits, sets up and maps it, no matter how good an ECU is, if its not set up and mapped spot on, you may as well have any old crap;)

 

Good point the Mapper must know how to use the software correctly and know the unit, other wise would take a long time to get mapped correctly and lots of visits to the tuner

And that's what would bump the costs right up

If you're not capable of mapping the Megasquirt though, the costs soon add up, especially as Ryan can supply the S6 as plug and play, but Megasquirt would require a bespoke loom. If you can do the mapping yourself, the obviously you could save a fair bit though this will not apply to most.

aussies like haltech while the yanks aem and motec

 

MoTeC, Autronic, ViPeC, Haltech, Microtech... all Australian brands, in order of price. My car was running on an Autronic SM4, but have switched to a Syvecs for VVTi control.

[Chucky_waR]

That's why I said "in the UK"

 

I'm sorry mate but I still don't see the difference between Supras in the UK and the rest.. I understand what your say and yes if I had a choose I would got motec but I can't.

 

And for your comment on "For anyone with a TT going single, by using a cheap ecu, you're demonstrating to potential buyers of your car that it was built to a price rather than a standard." what are you trying to say mate? That I'm just interested in building my supra with crap parts? Austec Racing build my motor so I'm sure it has been done to a high standard but the FIC is not an ecu I want to run my engine management. I will later go with something better like Syvecs when I can afford but for now something standalone with knock sensors is better than what I'm running.

[j_jza80]

What I'm saying is, that if you've gone to the expense of having your engine built by a good firm like Austec, why risk it all by using mediocre standard management?

 

Motec M800 is a good alternative to Syvecs, but they're a similar price with fewer features, so what's the point? I'm not aware of any Haltec specialists in the UK, so again it's somewhat an unknown quantity here.

 

With Syvecs, you get full UK based support, the best Supra mapper in the UK and they're also a UK company (which is important to me, though I understand that few people care about such things these days). They've been tested again and again here and I'm yet to hear of any serious issues. Try saying the same about AEM...

[a98pmalcolm]

The Syvecs unit its £1550 and then to fit and map with the extras is about £500 to your looking at around £2000 for syvecs why someones said "hes not looking to pay £3k" Thats ok then as Syvecs is £2k fitted mapped and supplied

 

You NEED to get a good ECU with someone that can map it incredibly well and will know the ECU there fitting and supplying inside out. I'm not mentioning any names but there's a few mappers out there that think there good, but really nothing special.

I'm not a mapper myself so I can't say what makes a good mapper but I can only talk from being a customer with experience and seeing what other people say...

Did ryan say he going to do a plug and play version you could install and he could check remotely? Save him coming over to Ireland for example?

I have just bought the Link G4 pNp ECU (the Vipec V88 is a rebadged Link G4) and I will be installing and tuning it at the end of this month, so will post feedback on it then. Three other Supras I know in NZ run the older Link G2 and G3 with great success.

nice one mate if at least to give a idea what to expect as this thread didnt go as i had hoped, as it is limited to what tuner you use

[V8KILR]

I have been using the PowerFC for the last 6 years with the FC-Datalogit software and even although they are getting pretty old now, it works very well. I'm making 600rwhp with it on my T70 setup which idles rock steady at 900rpm with 1000cc injectors and high lift 272 cams. It is simple and easy to use with full control over ignition, fuel, etc and supports the sequential setup as well. The only reason I'm changing to a Link G4 is to be able to run a flex fuel setup with E85.

 

Prior to that I used the Apexi SAFC II with 720cc injectors and a Greedy T78. It ran a bit rich when warming up but gave a good steady AF curve up to full boost. I would say this is a good cheaper option for the smaller single turbos and injectors up to 550-600cc in size.

 

With the Link G4 I will be running 1800cc injectors for future E85 use, and if it can idle nicely with those on pump gas, I will be very impressed with it.

PowerFC is a nice ECU, but they're starting to get a bit thin on the ground here now, and command high prices when they do turn up. They seem to be most commonly used on Hondas and RX7s here.

has enybody tryed or read about the emerald units? seem well priced

[mellonman]

The k6 has:

 

6xinjector, 6xignition, 4xtraction/abs, 3xmaps, can bus, wide band correction, egt correction, the list goes on. Vvti is also possible but not tbw yet. Knock control is on the todo list.

 

Lyndon.

 

lyndon is in talks with sorting a supra on maybe pm him

[add heywood]

Another Power FC user here. It actually came off Steve Linton's time attack car before he went Syvecs. They come in at around £800 with a commander. They are a good ecu, and I have been happy with the results, the knock sensor feature is a good one. Although Syvecs would be my prefered choice if I was ever to change, for 2 simple reasons.

 

1. Other people have shown that this is a VERY capable ecu, that always hits good numbers in a safe way.

 

2. The features on it are worth the extra money imo. To buy all the features separately would cost ££££ more (Racelogic, datalogging etc).

 

For the mappers in the UK, I have had Ryan and Matt from AFR both map my car. Both were very competant mappers, and got the car to where I wanted. I did like the setup at AFR when dude and Matt were there, as any mechanical issue could be resolved at the same point as mapping.

 

With Ryan and Charlie at SRR if any problems arose, the mapping session would be aborted and you would have to get things sorted elsewhere before returning to have mapping completed. Not a problem for the guys that live quite local, but when you are travelling a 400 mile round trip it becomes a big problem...
