Budget Ecu's

[zebra]

I don't doubt they are genuine

I would like an actual shop to either ring on the phone or walk through a front door for something like this

[stocker]

thats kool............i do all my shopping on the net

[zebra]

I do most of mine on the net too

But something as important as thing I don't want the muppets at aus post chucking in the back of a truck and letting it bounce around for a few days

[scotty nm35]

Thats a good price though, and i'm sure they could package it safely enough to be thrown across the room.

I just dont want to deal with AVO, VL Tuuurboworld.

Converts to $2k + post and no hand controller lol

paul the ebay seller use fedex for his shipping

hey guys i didnt want to start a new thread for one question so while we are on topic of ecu's my ecu has wasted spark feature what is wasted spark and whats its good for

Oh come on, what about google!?

I'll throw you a bone though. Wasted spark means the spark plugs fire in pairs. So one sparks during the compression stroke and the other sparks during the exhaust stroke. That spark during the exhaust stroke does nothing though, hence 'wasted'. The benefits of this is that you can halve the number of ignition components that you need, so on a 6-cylinder car you can use 3 coils, etc.

Ah I see I did google it but it didn't tell me the benefits

after many hours reading and downloading / playing with all the software etc

I have narrowed it down to 2 ECU,s

The Haltech PS2000 or the Adaptronic E1280

Both are around the 2k mark, So double what I originally wanted to pay, they both have cheaper options at a bit over $1k, so I have to decide if I really want sequential injection and ignition.

The decision for either of these came down to both the ease of use with the software (not saying the others are hard) and they can both be tuned via Speed Density.

Which for me doing the tuning myself makes it much simpler, I still think the Haltech software is the easiest/best laid out to use between the 2.

So we shall see

Edit - wait a min!!!! I disregarded the sprint 500 for its lack of big enough on board map sensor...just found out an external one can be fitted.

This changes everything!

Can now get an ecu under $1000 that also does VE/Speed density tuning!

[ARTZ]

and speed ensity tuning is?

[zebra]

Volumetric efficiency - you tell the ECU a target A/F ratio, engine size, the approx VE and injector size, it works out how much fuel to squirt.

then adjust the VE to get the fueling spot on

Pretty much means you can guestimate the VE to get the car started and mobile, then adjust from there, instead of working out injector pulse times

I'm sure someone will know more than me, but it is how they tune both R35's and LSx V8s with flash tunes

G4 Link ECUs can be configured to similar effect - not quite as refined as that, but still a lot nicer than just having an outright pulsewidth table.

Firstly, the fuel tables when using MAP as the load value actually are mapped relative to atmospheric – so you effectively are mapping all load zones as though they are at “sea level” atmospheric pressure, then the ECU calculates up or down based on what the load line actually is. If you see a G4 Link fuel table with numbers roughly twice as big around the 200kpa load zones as at 100kpa, then there are probably quite serious issues with the tune.

Secondly, there is a mode called “Open Loop Fuel” or something like that (I don’t have the Link software in front of me) which when enabled – does a similar type of offsetting, but this time it treats ALL fuel values as though you have tuned the entire map to suit stoich. The ECU then refers to the “Target AFR” table which is normally used for self tune and closed loop lambda to scale the numbers up or down to suit the actual target AFR you require for that load cell.

Sure, its not as nice as speed density tuning but really to me the main benefit for SD tuning, and this for that matter – is that you don’t have a map which is “all over the place” due to required pulsewidths going up in non-linear fashions due to load and AFR targets. Makes mapping that much easier, and you’re going to have to piss around with the base numbers a bit at various load levels regardless to get them running nicely.

Cheers. Do you happen to have a g4 map for me to look at? Doesn't matter what motor.

The SD factor just appeals to me because I decide to wire in an ecu I would need to easily get it running and do the low load points quickly

No doubt full throttle isn't all that much different between SD and inj pulse to get right

I do hear good things about going from a pulp tune to e85

Change the target afr and off you go. Or the adaptronic let's you change the lambda figure and go

I might have a nosy later and see if there is anything I feel like sharing, as I use that mode in all the G4 tuning I've do - as well as other fun things you might find interesting such as switching fuel and ignition maps in real time (on VTEC Hondas) etc. Fwiw when you download the G4 software you get a bunch of sample maps anyway - SOME of those have the open loop fuel mode enabled as is.

Can't really comment as I've not done an SD car yet, though the G4 cars I've done have typically taken similar or more time to get other configuration bits sorted (that aren't specifically fuel table related - ie, cold start/accel enrichment etc) than to actually get the car running and driveable.

Same would apply for the G4 with the method I described of course, with the added advantage that (providing you configure the O2 sensor setup correctly) it also has support for using input Flexifuel sensors for fuel and ignition trim

Ye, I do really like the Link/Vi-Pec ecus.

not a huge fan of teh software, PC-Link is better than the vipec despite been 99% the same

Im sure that is more to do with me playing with every available ECU software that is out there lol

The Adaptronic software is fine on a 19" monitor...not sure how it would go on a little note book though....too many small tabs to click on

This is hard to beat Feature/$

Flex fuel, Speed density, In build knock headphone jack + knock control, and their predictive map feature

[Lithium]

Interesting, will actually have to look at them a bit more for informations sake if nothing else

[zebra]

Yeah they are a good little unit. Software feels like it is 10 years old though

[ARTZ]

Yeah thats the puppy i want...tempted to palm of my PFC for one...

Its the one HG sells with the turbos isnt it..Is there a plugin loom for skylines?

or is it this one im thinking of
