Budget Ecu's

[N I B]

I have a V500 in my Racecar and its all good. Support it the only problem in many states.

How about a megasquirt?

not a chance in hell lol

I would rather an old dial tune microguess

[Hanaldo]

I'm sure it works ok...just prefer the idea of scaling the load points by manifold pressure x rpm, eg max 10psi boost, so scale the load points from say -14.7psi to +14.7psi

that way I know what I am looking at in regards to setting up a target AFR map, or even just punching in a rough timing base map (will be road tuning a lot so will be tricky to hold a steady state load at high rpm)

Is that even possible to do? The load scales are arbitrary, you can't accurately represent boost or vacuum with it. It's simply a theoretical calculation done by the ECU based on several other factors.

At least that's how I understand it to work in the Nissan world, I assumed other ECU's would use a similar theory?

I found that Emanage Ultimate are not to bad especially in an auto as piggy backs are a bit limited. I ended up getting an Emanage Ult with proper harness to suit rb25det for under 900 via ebay ( just look at for the american sales as they are cheaper ) and that was new with warranty.

Ive had one before...wasn't a huge fan, as you are forever fighting the standard ecu.

It is still an option, but for the money the value isnt really there

... because 100% load on a 250cc motorbike will be way different to 100% load on a 600rwhp 1jz powered commodore ute - I'm sure it works ok...just prefer the idea of scaling the load points by manifold pressure x rpm, eg max 10psi boost, so scale the load points from say -14.7psi to +14.7psi

You realise 14.7psi on a 1JZ Commodore ute and 14.7psi on say a 1EFTE Corolla are also way different?

Fwiw, if you are doing a reasonable amount of work with a car and suspect you will have it for a while - seriously I don't think you should skimp on the ECU, especially if you anticipate learning.

I personally found the G4 Link software quite intuitive , there is a LOT of adjustability which can mean a lot to track down and keep an eye on - but with tuning ignorance isn't bliss IMHO. The help system is pretty good, and again its worth getting a good look over what there is going on and what needs to be considered.

I've done a reasonable amount of playing around with a GReddy E-Manage Ultimate and they seem pretty good, albeit being a pita not running on Windows 7 systems (well, last time I tried to install it on one).

I've tuned an NA Honda on E85 to make >190kw using one and it drives more or less like stock and makes the numbers, so they can do the job - there is the bonus that the factory closed loop, diagnostic and knock systems remain in place as well.

On the down side, you end up (whether you like it or not) getting well familiar with how the ECU you are signal intercepting for does its thing and have to/should leave a margain of error you may not need to worry so much about with if you had full say on what is actually doing.

They are quite easy to set up, just make sure you understand what is actually happening when you tinker with whatever you go for as the potential for fail is high.

Yeah I don't like them as a preference - but they'd be one of the cheapest options on the list. Other things in a similar price range will likely be other interceptors which will have similar issues, or something which doesn't have "the whole package" included and likely to have extra costs and work involved in getting a fully functional solution which eats into the value for money imho.

I've been most impressed with Link G4 Atom as a semi-budget solution, still a quite powerful ECU - and sounds more than capable of what you are after by the looks of it.

Ye I realise the airflow is different etc, its just the way I like to look at the maps, seems to sit with my brain better lol

as for the EMU, a lot of toyota guys have had success with them, as the JZ ecu's dont have all the weird protection crap the RB25 ecu does (r&r etc)

You are right, they are easy to setup, I think my issue was (on the RB25) was 740cc injectors and a Z32 + larger turbo, I just dont think the EMU could hack the changes, It went quite well with the standard injectors and MAF though

The JZ being map based and having just a simple 1Bar fuel cut and knock retard may work quite well.

Wont be going crazy with mods, maybe 2J 440cc injectors for stock turbo E85 goodness.

Want I want to do is max the potential for bolton's while running standard boost on the standard turbos, so instead of upping the boost to make power (and probably have another turbo let go) I will leave the boost standard and tweak the tune for more power.

Sounds silly I know, but for longevity (track work etc) the less boost the better.

Hope that makes sense.

Obviously even an Emanage blue (which can be had for $380 with inj and ign looms) would do the job nad would be piss easy to use...but it won't really teach me enough about proper tuning, simply adding 1 or 2 degrees on top of the standard maps and pulling a bit of fuel from a very rich top end, won't learned me in complete in's and outs.

I really should get myself on one of the Haltech/Wolf tech nights that are held every so often

My EMU is running perfectly with 1000's on e85 so it can definitely work well. EMU can also get rid of the airflow cuts etc too. I found its good to learn with as the stock ecu esentially runs everything from the start allowing you to tweak fuel then timing. There was one with universal harness in the for sale section a while back for $400.

I do agree with Lithium, the link looks the pick and I will probably be upgrading to the G4 one day, just for the electronic throttle and cam control.

How does the emanage blue rate....bang for buck? I do recall trent running an Angry SR20 with one, but cannot remember if he liked how it went or not

If I just wanted 440cc injectors to run E85...from memory they can only add fuel and not pull fuel out yeah?

1 thing I have learnt from having a power fc and a wolf..... save time and money go the best option you can go within reason... I regret going the power fc over just spending the money for the ecu.

[The Dan]

Why not spend the extra $700 and get a Wolf V500 plugin. It can do everything you want including control your auto so you don't need to go piggyback.

[zebra]

I, would love to go a plugin Dan, but no-one lists the JZA70 (new car) as a plugin.

But you are right, I really think I should get the best possible..even if it means waiting 6 months or what ever it takes

I am pretty sure EFI's 1jz are all auto(Not 100% sure) but talk it out with Dan and Sean(EFI Tuner) Sean was pretty much the person who convinced me to go Wolf with the GTR.

Stumbled across this just now, price is certainly good.

Not sure too many mobs in aus would be familiar with them though.

The Same guys do a plugin patch harness for both the EMS Stinger and the EMS 6860 (little more expensive)

[STATUS]

Adaptronic, on your setup.

So many differing opinions, but all saying the same thing

So I will up my budget and wait a while longer...who knows maybe even a super rare jza70 pfc will pop up cheap.

ERD Dan spoke to wolf for me, said they (wolf) are happy to create a plugin harness for me, that to me says a lot, and actually surprised me a bit that they would be willing to do it for a single car. I'm sure a few of the other ECU manufactures would do the same I just never looked into it before.

if we can reliably make well over 900hp from a PFC.... what shortcoming did you find that we didnt? question not criticism.
