Re: KA24DE (NA) swap no start condition.

Glad you at least got it running. Having to turn the FPR down to 10 is aweful. There must be an input causing the ECU to drive the injectors that hard... Do you have consult or similar to see the live data? How are your voltages at the ecu, at the alternator, and at the battery? If your ecu is readi...

Re: KA24DE (NA) swap no start condition.

Sounds like you're heading in the right direction diagnosis-wise. If you unplug injectors and it can momentarily start on carb clean then your ignition is at least good enough to start. Sounds like you need to look at those injectors closer. Are they stock? Does your ecm have a custom tune? The only...

Re: Head gasket issue?

Sounds like the head may be warped and need resurfacing. Check the block (usually okay) and head with a straight edge. Also check for any marks from "aggressive" sanding/cleaning on the head surface. I would give the the cometic one last try after addressing the head. Many people are able to reuse t...

Re: Nistune strange injection time issue

When I look at your primary ignition map there are areas flagged for knock detection. I must be missing something else? I'm only bugging you about this because the issues fits if it is at least still using the fuel knock map, which you have zeroed (14.7:1 AFR). This would make it lean until knock we...

Re: Nistune strange injection time issue

When I look at your tune in tuner pro I see the knock sensor box checked. I am not sure if Nistune handles that differently but it seems odd to me. Do you have another tune with the knock feature enabled or with the secondary maps in place?

What RPM does it happen? It happens at any RPM when apply throttle. Any load I apply at any RPM causes the AFR to go lean and then back to normal.

Also consider using an N60 maxima MAF. It will give you more stable AFR versus the G70 one and it is less restrictive.

Re: What's the right way to clean AEM Map sensor?

Pretty sure you cant clean them, its a small hole with a diaphragm. Make sure the tubing to it isn't plugged/kinked.

It might be helpful to list the details of the problem, maybe someone has come across it before.

Re: Water/Meth instead of ECU tune?

I'm with Matt on this, learn to tune a little and the injectors won't hurt your MPG at all. Actually you will gain MPG with a little dyno time to dial in your cruise timing and AFR!

Edit: Forgot to mention that you are cruising in top gear 90% of the time, so that's where your MPG concerns are.

Re: no idle switch in haness?

My guess is you have an AT TPS but a MT harness. If you are running a manual trans dont worry about it, the ECU uses the TPS signal for idle (<0.52v = TPS closed).

Re: Odd Limp mode Z32 MAF troubleshooting

Your MAF can't work without power.

The MAF gets power sourced from the ECCS relay which is what gives your ECU power. So if the car runs that is fine. You need to find out where the break is in the harness or run a new wire from the ECCS relay. Double check wherever you have messed with the wiring.

Pull the injectors one at a time to find out what cylinder is causing it. Check compression on that cylinder, check the injector or replace, check/clean the cap/rotor, swap plug wires or use a spare.

Re: D21 ECU

Unplug the 4th and 5th gear switches on the transmission and your problem will go away.

Most switches will connect to ground when on. There is no way for the computer to detect if the are unplugged. Electrically they appear just like the switch isn't activated.

Re: Dipstick tube

Where it goes into the block there is a flange. I think if you grind the flat off of that you can spin the tube around, see if that might give you enough clearance. Pictures help too.
