Yep... any factory 28pin Nissan EEPROM (and other manufacturers with 28pin eeprom chips for that matter) can be modded.

I've got a VH41DE and I'm gonna socket & mod my EEPROM as soon as my car is together.

I am trying to convince a mate of mine to do a VH45 swap into an S14 also. Twin GT35R turbo's though. Even if he uses my spare engine for the time being. So be it. Mine will be a running before that takes place though.

I am now just waiting on 7 conrod bolts. 9 arrived instead of 16. And the inner valve spring seats

When my project gets underway I'll be sure to give you a call. I'm all about reflashing. We had to socket my Skyline ECU a few years ago, worked very well. I'll be in touch...

I was looking at the underhood room, a set of twins will be tight. One big TO4R or maybe the new TO4Z will be my choice.

With a little narrowing of the diameter, the inner spring shim from the intake side of a VG30 will work. The VG30E inner spring is wider, but the shim has the same clearance on the guide as it does with the VG30E.

When I was looking for an ecu, the microtech couldn't even do 8 cyl's sequential injection and 8 ignition drives. The linkPlus was easy to program and did the bizzo...also the guys are helpful and great to deal with.

i dont blame you for using link since you are from NZ

you'll find microtech can do whatever you want ... you just have to ask

8 + 8 isnt available as yet though

Well sorry to say at our shop we wont even look at a car fitted with a microtec, heltech or wolf these are all greif and not worth our time, link is a good thing and well worth a look motec is the best ecu you can buy and worth the price hey the M4 is all you need my car runs an M800 and makes 567KW at the wheels, an EUC will make or break your engine so purchase the correct unit from the start. I have seen many customers regret there purchase and spend more money to change to something better later regards Advan Sydney

Acutally you'd change your descision about motec being the best untill you went and took a look at bosch motorsport ECU's there atlease 2 to 5 times the price of motecs m880.

I just wonder whether it's the TUNE and not the ECU that breaks the engine normally. The ECU is often blamed for engine failures not the tune (or the build itself).

I'd agree with that, ultrapulse. The ECU isn't capable of breaking an engine, it's the signals it sends... and it only sends those signals when it's programmed to.

This is why I support the 'retune the factory ECU' camp... it's the ECU that came with the engine and is already completely configured for every device & function in the motor, all you need to do is retune all the mapping. It's cheaper and less risky than moving to an aftermarket unit.

In saying that though, if I was offered a MOTEC for free I sure as hell wouldn't turn it down! Ezekial is no doubt gonna blow us away with his setup when he has it up and running & tunes it up ! I expect videos !

We do a regrind to ~264 9.5mm lift.Avail of cam billets is reason for not having replacments. Cost is prohibative.

What about the VVT cam phase gear? Honda K20 engines have the same thing there's tons of cams for it.

Its just a matter of having them made.

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 pretty shure you can swap a biki daughter board onto those particular ecu motherboards.

well sorry to say but look at your market. people with too much money and no idea. this is NOT an insult by any means. its just the truth.

i am yet to see any advan cars run quick times in comparison to what cars with microtechs run. how does that s14 run compared to say ... dale's rb30/25 one with the microtech? but hey you are preaching to the converted. I have an M800

I've seen a Chrysler K car run high tens on a a multi staged fuel injection system that cost less then 500 bucks. I've made 498WHP with a RB20 and a variable spray alcohol injection system I tossed together myself. Neither was by far a "good" tune, but both worked.

If I have access to the fuel map and a wideband I can tune any car to make a ton of horsepower with a fairly safe tune. No it won't be as good as a microtech or AEM EMS (which for the record is probably the best system on the market) but they both work. A SAFCII combined with a MSD BTM for retard on boost will yeild very good results for a beginner.

For a car like Ezekials...I'd run the AEM EMS, simply because of the amount of work thats been involved with the project. I, on the otherhand, will only be maxing out the stock internals, so a rom tune or inexpensive ECU is quite ok.

Peace WD

how does it run.... street tyred, pump fuel, stock turbos no gas and it ran 11.2 at 121. The car is not the sort to be compared with as Dales car runs slicks, C16, nitrous and a big single. Our S14 will need some sorting but it will go fast soon. The owner of the car doesnt want to get booted fom WSID just yet so isnt fussed that it hasnt run that magic 9 second pass. Does Dale know exactly how much power this car makes??? i hear he isnt even able to strap it to the dyno properly to get an accurate figure??? we know exactly how much power our S14 makes and let me tell you, Dale is a little behind the 8 ball!!!

For those that may think Link is junk..... we run links is almost all our high power street cars. All make in excess of 430rwkw without any problems and drive exactly as they should on the street.

We are currently in the process of working out what needs to be done to GRACER, we are converting it to a VH41TT AWD, and when it is time to order an ECU Link will be our only call we make!!!

Its also great to see you took my advice and went with a MOTEC!!! you wont regret 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.
