S12 VH45DETT Build-Up

OR you can keep it simple & just socket your eeprom, run the romulator & tune the ECU how you like, then chuck a burnt chip back into it.

I gess untill you have spent as much time as i have on the dyno with all types of ECUs you cant understand. But at the end of the day its all about your budget just remember a jumbo jet wont run on a laptop spend wisley

I'm sorry but I disagree. An engine only needs the right amount of fuel, at the right timing, with the right spark timing to ignite it. There isn't really anything else that needs tuning to get the most power out of an engine's setup.

All three of these maps can be completely customised at all stages of the engine's operation & throttle position, within the factory ECU (including a separate map for each gear, as well as high and low octane map sets). There is simply very little advantage to be had by using an aftermarket computer perhaps apart from increased resolution maps, which may serve to smooth the tune a bit by adding additional X & Y points in which to plot values, but if you're honest you'll admit it won't increase power.

The thing is, an engine is not a jumbo jet, and a management system is just a collection of around 10 sensors putting input values through a series of formulas, spitting them out the other end & applying them to the devices on the engine.

It's all fine and dandy for you to sit there saying how experienced you are at dyno tuning etc, but unless you can provide actual reasoning as to why spending $2k+ on a fancy management system gets better tuning results (as in, significantly better results to justify the significantly higher cost), then please don't try to tell me I don't understand.

Have you ever put a Nissan on the dyno with a socketed ECU, running a romulator & romtune software on a laptop ? Honest answer required please.

[elwesso]

Here is the difference:

The factory ECUs are harder to reprogram, but aftermarket ones are easier to customize.....

You can do the same thing, but if you want to spend 2k on an ECU that is easier to tune, thats fine... Most people will be able to tune a lot of aftermarket ECUs but it takes a lot of SPECIFIC knowledge to tune the stock ECU....

in SOME cases its better to run an aftermarket setup, but still if your going to run an aftermarket.... It all depends if you tune with your checkbook or that thing above and in between your shoulders.

[Mettler]

Thank you Wes, and I'm sure that as the software used for programming factory eeproms is updated & improved, the ease of tuning will increase with it !

OR you can keep it simple & just socket your eeprom, run the romulator & tune the ECU how you like, then chuck a burnt chip back into it.

You could I guess. The only thing with chipping is inserting new ones, (when ever a tune isn't fine tuned). Reprogrammable daughter boards are a one time sauder. Then retune as many times as needed. Also more convenient when you are on the dyno with a laptop it is direct plug and play when it comes to changing maps and scales while on the dyno. I just look at it as more of a convenience factor since the board is only $250 with the software, I don't see any problems. But if you have already invested into ROM burners I could see as to where that is more effective for your self. Both use the same programming as far as OEM tuning is involved, Flash Chip and daughter board are the way to go for convenience.

[Mettler]

Well you can erase and flash a new *.bin onto a chip, that's easily done... still the hassle of opening up the ECU to do it (four screws >_<), however I've been thinking of a means to plug a cable into the socket and have the chip mounted outside of the ECU casing, for easy access & removal, and ease of plugging in the emulation tools, or even leaving the romulator plugged in to run the ECU

Got a link to these daughter boards man?

Correct. The consult OBD system on the VH,KA and SR ecu's are the same. This means that the Biki daughter board can be implemented onto the VH ecus no longer than the 1990-1994 production dates for OBD1 systems.

[Stinky]

90-94 ecus use a 6303 cpu and a single 28pin eprom chip. The biki board is designed for the sr/ka ecus that have the cpu and rom combined in a single chip. A romulator or Nistune would be your best bet for the 90-94 vh ecu. I dont know about after 94. The biki board might work on those? Is that what you were saying?

[Bigvinnie]

The biki board might work on those? Is that what you were saying?

Yes. There are other motherboards that it works with Lucas the designer of the biki made it for the sr20det ecu's and KA ecu's. Other Nissan tuners have been modifying the biki for use with RB, and VH ecu's. Don't know how much truth too it there is, I just know the information has been floating around the biki and ECCS forums.

OK i have never asked for or received any advice from you nor would i ask or take any advice from ADVAN

I took advice from the likes of Phil Laird @ GSR and Simon @ Nizpro

Phil Laird.. the same one that went online and appologised to those that had brought his junk manifolds?Same Phil Laird that had cars run up to 5mph faster on STD manifolds than his.. yeah.. I'd be taking advise from him also...

[Ezekial]

no the phil laird that helped take archie's car to 6.99 @ 201MPH (mazfix) ... the first 200+MPH pass in the WORLD

and the same phil laird that took the QSR 4 rotor BMW from 8.8's @ 150ish MPH straight into the low 7's (7.29@191)

rotormaster and dyson have also dramatically improved their times from the aids of phil laird

check the above businesses websites ... and see if phil laird gets a mention?

not to mention the GSR 20B falcon which has also run 7's

picture speaks a thousand words ... you just got

Hi there mate gee i read this forum with a smile some of you guys are lost in space, i know i have forgotten more than you know. My company is light years ahead of you . You can play around in you garage at home with your $10 budget im happy for you . Just dont ring me or waist my time looking for info. From what i have seen on this fourm there are only a few guys who know what they are on about, they know who they are. You would be wise not to bag other companies. I bet you dont even know what 500hp is like so 1000hp is just a wet dream ,well mate we work with this sort of power every day and our projects do get completed and are drivern away.They are not towed to the scrap yard as junk, i will continue to watch the progress of your car prove me wrong. regards Skycat by the way i own Advan

[konatown]

I'd suggest revising your post to be coherent. It might garner a smidgen of respect out of the board members.

[Ezekial]

hahaha and a smidgen of respect would be a hard ask

news flash! nobody cares about your lame workshop or the lame cars you produce. when advan can produce a car that is within 4 seconds of the rest of the drag racing competition THEN let us know

your company is light years ahead of me? i'm a civil / structural engineer you twit

[Mettler]

If HKS can make a 300ZX run a 10 second pass on the stock engine, using reprogrammed stock ECU, then that's fine with me !

Skycat, seems to me that money is the only thing you understand, not practical & technical knowhow.

Ezekial, first 200mph pass in the world in what class ? I bet there have been faster passes.

[Ezekial]

yeh in that class ... obviously

for those not in australia ... advan is one of those companies who cater for people who think a bodykit and a BOV makes their car go quicker

[T45]

Damn! You australians and new zoolanders sure do have some big honkin ego's. I thought us americans were bad! Next you'll be fighting over whos dad has a bigger gun.

Anyways, keep it going! I am enjoying the convo...

[maxnix]

Damn! You australians and new zoolanders sure do have some big honkin ego's. I thought us americans were bad!

Yeah, and an aversion to spell checking.

I guess it's some dark comfort to know that public schooling is as bad somewhere else in the world. Why do I give more crediblity to those who can use English correctly? At least they can use declarative sentences. cogently.

Why we will all be speaking Mandarin in 50 years or be an under class of world citizens.

[Mettler]

I wasn't aware that there's a problem with my spelling or grammar.

p.s. You didn't capitalise 'cogently'.

Don't lump kiwis in with aussies, we detest that. Kinda like us likening americans with canadians, we all know how much you guys love that.

ah dont be like that Mettler , some of us Aussies are good blokes . We got lots of Kiwis livin here especially in your outer suburb of Bondi . No we are not going to make NZ our our 7th state ( yet ) .

[Mettler]

Haha of course Don, gotta love aussies... beer drinking, petrolhead, swearing & cursing nutters ! Couldn't ask for better neighbours

[Ezekial]

at least we're not dodgy tightarses

[velvet hammer]

hahahaha Advan was running an add for years claiming to be "sylvia" experts! (its silvia)They recently changed the add and now it says200zx specialists LOL OMGROFLMFAO GOLD!!

My Zeek knows more than you any day of the week. I would say I even know more than you except how to screw plastic bits onto cars and say that it makes them faster. Your Advan 500hp is probably 50hp with a pod filter really.

[Mettler]

Ok guys enough flaming, this is a reasonably mature forum... I reckon if you want to rebuttal someone, do it with facts and information, not name calling & personal attacks.

[Zeek's GF]

Sorry Metler, but I get mad when Zeeky comes home angry. He has worked hard on his car.

[skylndrftr]

getting back to that sweet motor ...

update?

[Ezekial]

oh dear ... lol

should have some photo's for everyone soon

[Ozzie]

Wow! Much flamage in this thread!

No 1: Regardless of what NZ'rs think, I love you guys.... I haven't met 1 kiwi that was an a**hole.... ever!

No.2: Advan has been known to be a rip-off.... Your reputation preceeds you... sorry. Don't blame me for saying it, I just tell it how it is. If you don't like it, do something to change the public perception of your company.. (Who the hell puts a TRD sticker on a GTR???????) You do know that TRD stands for Toyota Racing Development, right? HELLOOOOOOO!

No 3: Who cares what Ezekail's budget is...... He said he was going to drop a VH45 into a S12, and turbo it.... and he has done that. Kudos to you, for being a pioneer..... I wish I had the balls to tackle a conversion like that.

Back to the thread....so how's it all going?You know you need to post videos once its done ....right?
