Hi, just wanted to ask, coz Im not sure if I should go ahead with this yet, but yeah if I buy a remapped ecu that has been tuned for a front mount intercooler, when I dont have a front mount, is that bad? would I need to get a front mount for it to work properly? I found a tuned r33 ecu for a good price and just wanna know that it will work right with a more stock set-up.

The only mods I have are pod filter, and thats about it. The ecu I wanna buy has been tuned for a fmic and can run 15psi of boost. I'm currently running 10 psi.

Any input would be greatly appreciated. lol this is where my Krudd bonus is headed

<br />Just be careful, is its a Jap tuned ECU then it will be tuned for 100ron fuel, not 98ron like we have here.<br />
<br /><br /><br />

Oh really? well Im not sure coz the guy is from here and ran it in his car, said it was alright with the fuel. the ecus been tuned by top secret. but yah i just wanna know if running a standard intercooler will be alright with that ecu?

It'll be fine without the FMIC. All the IC does is cool the inlet charge and as long as you're not pushing big numbers all will be well. Relax and buy the ECU if it's a good price. I would.

Don't run the stock turbo above 14psi though, 12psi will be safe. I have a mate who's been pushing his to 16psi and she's still singing......

ok cool, but yeah forgot to mention, the turbo's been high flowed, but i personally wouldnt push it over 12psi anyways. the ecu's been done by top secret so im pretty interested to see what it can do. so ,cool as long as it will be alright then im sold. thanks man

<br />these premapped ecu's are a bad idea IMHO... they are probably tuned on 100ron and are for car specific mods<br />
<br /><br /><br />

yeah a few people have told me that. Dunno if i should just do a full remap of mine or go for a power fc, coz they cost a bit of money. And the guy i wanna buy from said it was tuned here, so it wouldnt be 100octane fuel. I was jus worried about gettin it coz i dnt hav a front mount IC and was worried if it would run wierd without one.

Weren't all those ECU's mapped on the premise of not only having car specific mods, but say an actual part number? And then you sent them back to Mine's, Impul etc to get them adjusted accordingly for more mods?

Having said that, a mate runs an Impul ECU on a bog stock RB20 with FMIC and 3.5" exhaust, and it goes so well for a stock RB20 we almost thought it had to have cams in it! Also dosen't detonate on 98 RON fuel.

I ran a Jap tuned Mines ECU on mine for a while at I had no detonation problems.

Even if there was a slight detonation, octane boost would sort that out in a jiffy.

A Top Secret ECU is worth getting, they are after all one of the best in the business.

Even if you get scared and don't want it Benzino33, point me in the right direction. I would snap it up without hesitation.

      @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
