I seem to remember somewhere way back I read (perhaps in the G35 manual) that if the ecu doesn't get the brake signal for a while it goes into throttle limp, not sure but keep it in mind if you do attempt it.

I worked out how to get rid the Emanage Ultimate ignition error code, it can be done inside the EMU box so if anyone wants the code gone, send it to me and I will upgrade it.

Mmmm..... Boobies!!!

My car pulled 5 more psi(so 15psi)by the time in hit 3,000rpm on stall..... Got there a lot quicker too on stall!

Launches hard!

Well done guys.

If you want to try it, its pin 55 on the ecu. Its a pink wire with a blue line.(around the middle of the plug.) Just make sure you tape up both snipped ends well. :thumbsup:

(Dont hold me responsible if you damage anything please.) lol.

Wouldn't dream of it ! I've already lost my ECU harness virginity. No big deal now :P.

I was going to run mine via a switch so I could break the connection or return it to normal at any time. Going to label it "Off" and "Fun" lol.

That way if there is any issue with the ECU getting suspicious after a while (hey, I just don't brake, OK) it is easy to fix. Throttle limp sucks :yucky: .

so use the emanage relay outputs to disconnect the brake line signal till around 50km/h

The good ideas have been coming thick & fast the last few days. Loving it :thumbsup:

OK, so some ideas are better than others, but you catch my drift, LOL

Aaron, to clarify a little on what the Impul ECU is allowing.

First, set the Informeter to recognise 100% throttle is 4.12V

Now, When I do a launch from a standing start I get around 45% throttle till about 10kph and then I get 100% throttle.

On a stall launch, I get around 45% throttle. (But this was not done properly as too much traffic around).

But I love :wub: this solution... looking for wire cutters on the weekend.

First Andy, try this out.

With your foot off the brake for a few seconds, try and launch. Does the throttle go straight to 100%? If it doesn't, unplug the throttle body for a few seconds and try it again. Mine definitely goes full throttle from a standing start without the wiring mod.

Then snip snip. :thumbsup:

I've been seeing some references to this figure lately and 2 questions come to mind.

1) I must pull out the manual & find out how to change this setting, and

2) why 4.12V?

By my actual voltage measurements on the throttle body & driving around, each 1V equaled 20% opening as displayed on the informeter. That makes sense if its default is 5V equals 100%.

If you are saying that the throttle does actually open completely, and this happens at a lower value than 5V (totally believable), then where did this magic 4.12V come from?

BTW, the max voltage I read was 4.04V so it's not too different anyway.

Even if it is 86% it wont make any difference to the power output, we have a massive throttle anyway. It may be done on purpose to swirl the air in the plenum.

Remember that the minimum voltage wont be 0v either. It is just the range of resistance the TPS gives.

Yep, from memory the minimum was about 0.6V at (cold) idle & maybe 0.56V when warm. I think you're right - guess it doesn't really matter if not physically opened 100% if the engine can breath all it needs. However, it would be interesting to see, via a camera, how the theory stacks up to reality.

If you could find a nice clear piece of 3 inch pipe to clamp to the throttle, you may be able to see it. The throttle opens to 100% in neutral and park, also without the wiring mod. (that was the other path I was going to work down if the snip didn't fix it.)

Are you going to be right to twist the wires together if it goes into limp mode tomorrow Craig? Or just restart the car I guess. Let us know how it goes mate.

no limp mode yet!....what am I the f#$king test mule?

Yup. :P

Don't worry Aaron, I have faith in my dodgy mods. lol.

oh trust me, if anything was to go wrong, knowing this Stagea, it would've slapped you in the face just as you are about to cut it.

Just frustrating it was that simple. lol

      Engine Issue

      By GTSBoy · Posted

      Resizing injectors in Nistune can be done a couple of ways, and there are a couple of ways that you can make a mess of it. The tuner needs to be really aware of the effects of whichever approach he uses (either K, or TIM). They are both easy enough to "get the injector size right" to run the engine. But little details like old start enrichment and hot start are affected differently, depending on which boxes you check.

      Pretty safe to say almost everyone that has tuned their own car has experienced this issue. The difference being that we have our laptop in the car and when it happens, it's literally 10 seconds of tuning to sort it.  Would you be happy to plug in your laptop and sort this yourself? It is a very simple process and there is no risk of harming your engine (if you are worried about that).

      Yeah thats the next step now, either they wil or i will take out for a drive to work and go straight their after work and see is we get the same issues 🤞  thought i try my luck here too, never know someone else might have had the same issue but thanks for the reply

      Basically your tuner needs to drive it for the 30 min (or whatever) to create the same conditions then check the ECU settings and sensors at that time. They may not be excited to because that takes them 30 min rather than just opening the bonnet and seeing the problem straight away.... Hot start is generally not as tricky as cold start, but there would be a table for fuel enrichment vs coolant temp as a starting point

      Yeah, they all cant say anything for sure as everything is working fine . Said unable to find an issue untill it stops again. Could mist likely be CAS wiring or IAS valve issue but again not 100%
