well if it is an auto r32, i would be looking at every option before converting to manual and putting a pfc in. there is a huge difference in price. especially if it is a r32. the cost difference between a r32 remap, and getting a pfc and manual conversion is a well over $1000.

i run a remapped ecu in my 33. haven't had any issues with the ecu.

I see it every day cost always comes into the equation but you know what they say you get what you pay for LOL !

i just don't see the point in spending over $1000 just to do a gearbox conversion so that you can get a new ecu.

[vr4sigma]

i give up man i cbf arguing i got work to do but just remember a few months down the track you will say remember that guy that gave me advice i should have listen to him LOL !!!! i know coz i made the same mistake but hey we learn from our mistakes sometimes you just have to let people find out for themselves

all i know is i always use aftermaket ecu's on our customers cars and we never have problems or complaints about the power output or the way the vehicle drives

cheers & good luck

well i have had the remap in there for about 4 months now. haven't had any problems.

a remap is basically an aftermarket ecu. it has all the same properties. it is tuned to your specific car. how good it is all comes down to the tuner. i know people who have gotten aftermarket ecu's and have found them crap, because of a poor tune.

how can it possibly be the same as real time tuning on the dyno , think about it , do you know anything about tuning ???? do you even know what you are talking about ????

so your remapped ecu is equal to a motec ecu ???

i dont see the pros using remaps ( v8 touring cars )

thats the dumbest thing i have ever heard

what mercury provides is what dr drift (sam) does. Although it is a remap, the tuning part is real time on the dyno.

[vr4sigma]

when they can be f**ked pluging in the emulator, but you still need to turn the car off to make the save LOL!

[ansch]

and how does that affect the end result of a tuned car?

[vr4sigma]

this is what shits me about forums theres always people who know it all but in reality they dont know f**k all

they have never put into practise they just know how to talk shit

to say a remap ecu is the same and a real time tunable aftermarket ecu is just stupid

show me some results i wana see a car with one of these remaps with some decent dyno figures just one car and ill show 1000,s of cars with aftermarket ecus that have made the figures on the dyno

dont you think apexi , greddy, motec, autronic, haltech,wolf and other the other ecu manufactuers can develop daughter boards and rom upgrades for factory ecus but they dont ???????? answer this question

coz it will never work aswell as a stand alone aftermarket ecu thats designed for performance not for driving to the milk bar or picking up the kids from school LOL!!!!

[vr4sigma]

and how does that affect the end result of a tuned car?

well first off it takes longer and cost you more money and the longer it take the shitter tune you are getting for you money if you know anything about tunning which it seems to me you dont ( have you ever road tuned ot dyno tune a car ) you would know that it takes a lot of time to tune a car to perfection

come back and talk to me when you have had 16 year experience ( when i was road tuning wolf 3d version 3.0 back in 1999 you were still in grade school

anyway if you guys like paying $600-$700 for $20-$30 worth of electronic parts and a map downloaded off the internet go for it like i said sometimes you have to let people find out for themselves

im not going to contiune this agrument as i dont want to offend certain people in the industry but i am entitled to my opinion which i have already voiced so thats it for me

cheers guys & good luck

I do not doubt your experience and no I have no knowledge what so ever of tuning a car. That's why I'm asking the question.

So what you're saying is remap will take longer to tune and if they quote 2hr to tune a car it would be a crap tune because 2hr is not enough time to tune it properly?

Sounds to me that it's more important to find a good reputable tuner who's got a good track record at what they do.

Personally, I'd prefer one with a bit of people skills as well. I am the dumb customer with nfi about tuning car afterall.

thats the biggest problem good tuners are very hard to find, and i can say what i have learnt , i have learnt from one of the best in melbourne

his very modest and doesnt like being in the lime light or being mentioned so i will not mention any names

if you go back to the same place then they can keep your tune on their computer, and when adding a mod to the car they simply change a few parameters and burn a new chip..

yep, so can you confirm they use a realtime programable rom emulator while the car is on the dyno i.e. realtime changes to the fuel and ignition maps? Then they replace the emulator with the burnt eeprom yeah?

Installing the chip, is just a matter of soldering a socket in place of the stock rom, this is a 30 minute job + $10 parts for the socket and blank eeprom. $750 is quite high as a up-front cost.

yeah but of course there is the R&D or licensing costs to recoup. I'd look at it from a results perspective. If i get just as good result as (say) a PFC, but for less, i'm a happy camper. Kudos to them for finding a cheaper product with a better margin.

how can it possibly be the same as real time tuning on the dyno , think about it , do you know anything about tuning ???? do you even know what you are talking about ????

Nothing you have said in this whole thread has made me think it would be ANY different to any other real time tunable ECU. IF they are in fact using a rom emulator that is capable of tuning fuel and ignition values with no lag time, then i cant see how it could be improved upon.

IF there was lag time involved between changing the values and the ECU re-reading them i.e. have to stop and start the car between value changes (or something crazy like that), then yes, i'd agree it would be a pig to tune.

dont you think apexi , greddy, motec, autronic, haltech,wolf and other the other ecu manufactuers can develop daughter boards and rom upgrades for factory ecus but they dont ???????? answer this question

Could be a number of reasons.

a) whole unit has more margin than a re-chip

b) they cater for tunes that are massively out of bounds for a road car

c) they want to add features not required on a road car i.e. anti-lag

BUt it's horses for courses. What i want (and i'm sure i'm not alone) IS a good road car tune:

a) stock appearance, or even the ability to quickly change back to stock

b) stock features retained i.e. cold start enrich, knock sensing, closed loop, traction control (if this comes from the ECU).

c) something thats tunable on the odd occasion i make a mod, not necessaryly after every saturday at the test'n'tune

Sounds to me that it's more important to find a good reputable tuner who's got a good track record at what they do.

agreed...i'm hoping to hear some real world stories about tuners using this method.

there are plenty of people on here with remapped r32 ecu's.

sure an aftermarket ecu will give you better gains that a remap, but for cars with only a few mods, there would be very minimal difference, since the remaps adjust both afrs and timing. how is that different to a fully programable ecu?

it is all about $ per kw. if you can spend a thrid of the money and come out with a tune that is within a few kw across the whole rev range then it is money well spent. for a relatively stock car a remap will be more than adequate, provide very similar gains, and be a fraction of the price.

i know that i wouldn't pay $1500 if i could spend $500 and come out with pretty much the same result. i would put the other $1000 into doing something else.

i agree with you its horses for course but i have had problem"s with r34's and dont recomend this untill the problems have been ironed out

http://www.skylinesaustralia.com/forums/in...c=78893&hl=

read this thread

r34 ecus have a fail safe that cause the engine to go into rich retard to stop the engine from grenading and the worst part is if retard not enough but it also richens the mixture which also causes retard by adding extra fuel you see when you add more fuel what you are doing is making the fuel burn slower which in turn retards the timing so in reality its like a double retard

must say a good topic...didnt even know it could be done good work lads

[MerlinTheHapyPig]

holy crap, this has turned into a sh1t fight.

vr4sigma, in response to some of your concerns,

Remap Tuning,

you can do:

1. Real Time Map Tracing

2. Real Time Map Editing / Tuning

With the right software and hardware, you can tune just as easily as tuning a power fc or wolf.

Maps and settings you can edit include:

1. Ignition Maps (normal and 'safe') 16x16 maps (you can custom set load and rpm points)

2. Fuel Maps (normal and 'safe') 16x16 maps (you can custom set load and rpm points)

3. Airflow meter mods (changed afm, running 1 afm instead of 2 etc, running a map sensor in place of afm)

4. Injecter trim, null time

5. coil pack charge time

6. fuel cut / rev/ speed limit

7. closed loop control

8. idle fuel/timing/target rpm

9. temp enrichment

10. Support for automatic transmission timing retard logic.

Now, what can your wolf units do which i haven't mentioned here? why will the tune, power or driveability with a wolf be better?
