Ecu Choices

[daz32]

Hey i have been trying to decide what ecu to buy for my rb26 conversion. I know alot of people say talk to your tuner but mine said but what ever you want and ill tune it,

How ever he does perfer power fc but i dont want to use airflow meters and the d-jetro requires me to drill and tap the runners which is something i would rather aviod as its a pain in the ass to get the inlet side off a 26

so i have been looking at a link G4 or the haltech Platinum pro but i cant find any info weather they require the same type of drillind tapping of if you can get the map sensor from an other source

any info would be great

Thanks Daz

For the little extra that somethinkg like a Link G4 costs it really is a no brainer.

If you get a D Jetro PFC, factor in the cost of installing the 2 MAP sensors (Intake off and back on) you would be damn close to the cost of a better ECU.

Despite what people say, the newer ECU's drive alot better than the FC. At the end of the day they are a old ECU. They will do the job...but for what really is an insignificant amount, you can get something that is alot better.

oh yeh nice do you know anything about the map sensor hook up does it require tapping the manifold? i have read people just t-ing the fuel pressure reg line for the map sensor

[Piggaz]

No tapping required. Just run a line from anywhere really. The shorter the better *in theory*.

awsome thanks heaps for the info now to get the ecu i was thinking of going the halteck as i wouldnt be stuck with a gtr ecu without a case

anyone know of any good deals on a platinum pro?

Wrecker?

Use the standard case?

Wrecker?

Use the standard case?

I think he means what does he do with the MB/ecu after he uses the case for the new computer

PS, push them f**kers to get your motor done so we can see the results

Autronic all the way....

Dropped off the standard buckets today and sump.

Let's see what the baby -5's can do. 450 or bust!

Its probably not easy to get at but that housing underneath for the IAC motor would be a good place to consider .

Plenty of people here like the Vipec or Link branded plug ins and MAP source aside it seems like an easy install , they come with start up maps from memory .

Personally I don't know Haltech any more since they moved from Taren Pt so I've not kept up with their products and software .

I think its fine to look at a range of computers and their various functions but at the end of the day its not what it has but how well it runs your individual engine . Dozens of unused features achieve zip . Different tuners know different products and generally get the best overall results from systems they know and like . Its probably not unrealistic to find a tuner you are most confident with and go with their recommendation . I think you'll develop a better working relationship with them if they supply fit and tune the thing inhouse . Really if you make it easy for them to do a good job generally they will .

Or you can run around buying a bit here and a bit there trying to save money and risking having to run around all over the place if any part fails to deliver .

If they supply its their problem and with systems they know and like they know the issues ahead of time and have them sussed or spares for known issues . If you give them something they are unfamilliar with they have to spend time working out the hardware and software and thats something someone has to pay for . Fixing unexpected problems is walking cane stuff and your the one without a car while all this is taking place .

I suppose if you already have a good relationship with the supplier/tuner you could ask what fiddly time consuming things can be done ahead of time to make the changeover easy - like a MAP tapping point . You might change filters and plugs and maybe fuel pumps do an oil change etc .

I hear a lot of dyno time goes into solving existing problems .

All this assumes you do things properly because if you're unsure leave it to them , mechanics hate backyard bodges and don't tend to respect those responsible .

Your call , I'm running a PFC and if I wanted something better I'd go ask Insight for a Vipec V44 plug in . People I know get good results with them and Scott is familiar with the product .

PFCs are a good product but a bit dated nowdays . They do a reasonable job but todays engines are a lot more refined in their running characteristics and a lot of this is because they used sophisticated engine management systems - and tuning strategies . A good aftermarket system should be able to run 90s era engines as well if not better than the original system did if they are firstly capable and secondly tuned properly .

At the end of the day you should get back a safe and usable car because it has in theory been worked on by professionals , just make sure you go to known professionals who have happy customers .

Just my views , cheers A .

Well, i can speak from experience with a Vipec. The ecu works, does as its told and is like most other ECU's out on the market today, HOWEVER, the customer support from vi-pec is insanely good. I have called ray hall on a weekend and he has answered the phone, had a good hour conversation on the phone, and done it with a smile. I am in the process of getting the ecu's on board map sensor changed out to a 7bar item, and you know what its costing me? Postage. The guy is a bloody legend and knows his product very well. Ill go in to bat for the thing purely on the customer support i get from him

Edit : Vipec increases your eretile capacity - and car runs sick too - do it ...
