how been done remap on stock computer ant what bhp did you get max? Today I been talking with Steve from FCtuning and he said that I need aftermarket ECU to run what I want.

 

at the moment I got 370-380bhp at 1.2bat with stock injectors and stock intercoolers. I want to put over 430bhp after I put 555cc injectors and bigger IC but Steve said that I can't run that power on stock ECU I need aftermarket one.

Is it true ? I am always was thinking that stock ECU is ok for 420bhp.

Get either a John Dixon chip, Zedworld chip, and there is another available as well, you would be better off getting it chipped if your planning on that. I'm using a Greddy ECU in mine running 16psi which is just shy of 1.2 bar.

Erm your ECU can run those goodies no problem, providing it's either mapped for them or chipped, but absolutely no need to change the actual ECU itself.

 

FC Tuning just map your car once you have done all your upgrades, so some confusion going on there between the 2 of you fella.

But What is the right way to do 420bhp? Is stock ecu with chip will be safe as remap? because what Steve said it that I running 1.2 bar on stock injectors and ECU and that is damaging my engine is that true?

Your turbos cant handle 1.2Bar, your stock injectors cant handle that much either!

 

To do this safely you will need new turbos, injectors and a remap (John Dixon, DTA, etc etc).

Ah now it's changing a bit lol

Running 1.2 bar on stock everything including the ECU "MAP" yes will damage the engine, eventually.

 

It's not the ECU you need to change at any point, but the actual ECU standard MAP, get me ?

You'll get 420bhp when you do the usual upgrades and either MAP the existing ECU MAP or have it chipped on it's own.

Turbos is not stock is pe1420 is no shuould be no problems at 1.2 bar. What steve said that than I will put 555cc ant bigger intercooler I still need better ECU. I heard also that stock ECU is ok with chip.

thanks for help. what power you guys running with what mods?

Complete and utter load of Shit, he is just trying to do you out of a ton of money to sell you a "new ECU", Just get your old ECU remapped for the mods you have applied.

So the best option is to get chip and remap stock ECU Is that right yeah?

How does sale chips and how can put it in?

Ok lets start at the begining.

 

You clearly want bigger power, you can chip the ECU at ANY time you like to increase power.

However you already have turbo's, i imgaine you already have induction kit and decent exhaust.

So yes bigger injectors and decent intercoolers is next on your list.

 

Now in order to run the bigger injectors you will need a chip to suit it OR remap the existing ECU on the rollers, bare in mind the car will not even run right once the new injectors are fitted until you either chip or remap the ECU.

 

So my suggestion is simply purchase a chip to suit your bigger injectors from either John Dixon or DTA. Zedworld do chips, but i don't think they like selling via post as they cannot assess your engine before fitting.

You can purchase the chip already fitted in a Standard ECU for about £120. You then send back in return your old ECU ( you can ONLY do this at the same time as the injectors are fitted)

 

Having done all this, if many months down the line you really want to extract the most from your upgrades, your car is Mapped on the rollers and you sell your old chip to someone else.

 

Finally, i really would suggest having your engine fully checked over by someone who knows what they are doing, a little while ago you thought it was completly broken. Remember these engine are now very old and whilst strong, you never know how much abuse it received from day one.

 

Hope that clears it all up for you!

...bare in mind the car will not even run right once the new injectors are fitted until you either chip or remap the ECU...

 

to add to all of Smithy's good points, when you change the injectors you need to change the chip at the same time, it will likely not run at all otherwise.

stock injectors, stock intercoolers, stock map and upgraded turbos running 1.2bar!??

Healthy engine :(

OH that's really good information guys. I understand all this much better.

I will check my ECU is there any chip in, just want to make sure in case. But if injectors a stock and turbos running 1.2bar if ECU is now with a chip does this doing anything or not? do you understand what I mean?

you will most definately have a chip otherwise your engine would have grenaded by now flowing that much air :)

 

ps 1.2 bar on stock turbos would max the injectors, 1.2bar on PE1420 would flow even more air so you're already on dangerours ground ...

But I heard that one guy is running 433bhp on stock injectors so than how does this possible ?

I didn't anything about power levels...

have you done anything to the internals mate ? for running high levels of power a forged engine Pistons & rods is a wise move ...although the rods are forged i believe as standard ...still changed mine though just to be sure ...only way to get more power is to increase the air fuel mix ...the turbo's provide the compressed ( increased amount of air ) which needs to have increased fuel to make the mixture combustable ( hence the need for larger injectors ) to tell the larger injectors how much fuel to put in the ecu reads signals from MAF etc etc and increases or decreases the duty cycle of the injectors accordingly ( that is very simplified but in a nut shell ) ....so an aftermarket chip is generic where they all are the same give or take a few bhp and it is fine for your needs ..but to get the most as Smithy says you can have the car mapped ......where the ECU is fine tuned in real time on a rolling road to the specific cars set up and each map would be slightly different the injector cycle ,boost , etc can all be set up accurately

an aftermarket ECU is only for those who want that bit extra ...launch control, built in boost controller, NoS control, switchable maps ( hi . med . low boost ) if you are shoving that much air in the engine and on standard injectors then you will be running very lean and getting very close to Det point and a fubared engine....turn your boost down until you get the injectors and chip at a minimum..and at levels of power above 370 the stock clutch is starting to strugle so that will need upgrading...also hope you have upgraded the brakes its no point in going fast if you cant stop.....hope that helps

Seriously I be honest this answer is one of the best. I will copy and and will print out. Thanks for all info so now I 100% what I need for my car INJECTORS, ECU CHIP AND INTERCOOLER. How is selling chips?

Glad you got there mate :-)

If yer mean who sells chips, as said before John Dixon on here and DTA, these guys will send you an ECU with a chip fitted, you then send your ECU back in return.

That way you know it's fitted correctly.

 

Zedworld also sells chips, however am not sure if they offer this same service, best ask. I know generally they prefer the customer come to them so they can assess your engine first, then fit chip and road test etc.

MY be is sound funny but how I can contact DTA or John Dixon ? Got any contacts? where to send and how to pay.

You will find all of DTA's details in the Traders section http://www.300zx.co.uk/forums/forumdisplay.php?f=42

 

and you can email John dixon from his profile - http://www.300zx.co.uk/forums/member.php?u=239 (go to contact details tab) , of you subscribe you can Private Message him.

thanks I hope so my car will be ready and everything will be done by summer.

steve does not use an aftermarket ecu, he solders a nistune daughterboard into your stock ecu which makes it fully reprogramable, this is 100% as good as it gets as far as mapping goes without using a full aem or similar setup. my car has been mapped by steve and on standard injectors, turbos and internals made 437bhp.

Were you running neat ethanol to get that figure? Or even hydrogen?
