I started a thread May 2010 on the ECCS forum asking for interest in running a KA24E with a 16bit ECU and TunerCode and didn't get enough interest to justify a full development. There are quite a few code mods necessary to make it work.

ECCS 16bit on KA24E Thread

program looks good...but I didn't see where it said if its for a SOHC or DOHC, s13 or s14...will that program work for all of the 240s, or just specific ones? Sorry if I'm blind...been at work for 10 hours already and my eyes are starting to cross since its closing in on 5am Excellent question. Sup...

Have a look at the Nismotronic NEMU Tuning Package before you make a decision.

In this case, TP stands for Theoretical Pulse, which is proportional to the calculated injector pulse width necessary to produce an AFR of 14.7. This value (TP) is an integer used as the load scale in the fuel and timing maps shown in your screen shot.

Dave

The stock ECU definitely uses this method to stabilize idle. It uses 2 separate tables, one to retard timing when idle speed is too high, and another to advance timing when idle speed is too low. These tables combined perform exactly the same function as the "Ign vs. Idle RPM table" pictur...

The board hardware and supporting firmware are still in development. When that part is done and tested functionally, then environment testing can begin. Please be patient as John and I will keep everyone updated with our progress.

Thanks,
Dave

Price will be extremely competitive, unsurpassed "bang-for-the-buck". Fan control, launch control, and many other new features included. The pic is just to let everyone know that it's on the way. Details WILL be forthcoming.

Moates is developing a new real time board that will program much like a stand alone with Nismotronic and TunerCode. More info here: http://www.sr20-forum.com/tunercode/456 ... oards.html

This is kinda along the same line as what you guys are doing but I want to find out what I need to add a pre-tuned chip to my ecu. I don't think I need Calum or Nistune or anything like that, I just want to be able to run a rom tuned chip in my ecu. Do I need a " daughter board" or someth...

Replaced any light bulbs, or any other maintenance lately?

Now that you say S14, the problem you are having is probably because the OBD2 ECUs use a hybrid method to determine fuel requirements involving multiple maps that is not well understood. I hope to have a TunerCode solution for OBD2 sometime after the new RT daughter boards are available.

Dave

If you are using TunerPro, sounds like it might be an XDF problem.

Dave

If you intend to run closed loop (using O2 sensor for feedback), then you can only tune (modify) the open loop portion of the fuel map. Changes made to the closed portion of the fuel map will be tuned back to 14.7 AFR by the feedback control. If you want to run open loop all the time, then you must ...

Interesting point. I haven't noticed this phenomenon, but theres also map tracing in Nissan Datascan with the consult cable. Does the maptracing feature on datascan suffer from the same deficiencies? It's reading right off of the ECU... The reason you haven't noticed the phenomenon is probably beca...

There are a number of problems using this method to log and map trace with one TP value. The ECU calculates a TP value based on the MAF sensor, RPM, and K constant, however this is not necessarily the TP used with the fuel and/or timing maps. Under certain conditions, TP comes from either the TPMin ...

You may want to watch out for Steve at Rom is Burning too. He is a TunerCode dealer, but hasn't payed for the TunerCode licenses he's sold.

AEMTuner says output pin LS6 is assigned to both A/C Clutch and Fuel Pump #1. It also warns that output pin Idle 3/4 is used as a general purpose output, but is in an "always on" state.

Bad gas/fuel filter maybe?

...also in addition to MS you also have TunerCode and its derivative Nismotronic. however ive only done a bit of reading on that. seems to have some good features but from a feature standpoint MS has many more options including the biggest caveat i can think of is speed density (map sensor) based t...

The ECU adjusts timing during idle for idle speed stabilization, so that is normal. Timing is pulled as the throttle is opened, based on how quickly the throttle moves, and also during overrun fuel cut, so that looks normal too.

Did you check the ECU for codes? Could be a CLT problem.

Dave

The MAF should be grounded at one spot on the intake manifold. Having two ground points can cause problems. Dave I have to ask this, 'what do you mean?' A ground is a ground. Also the Intake is Aluminum, and that can't be a good ground. Maybe you can explain a little more in depth. No two ground po...

If there is a problem with the MAF, the ECU uses the TPS and RPM to determine TP, so if both MAF and TPS are giving bad signals, things don't run well.

Dave

How old is your fuel filter?

I wonder if something like this would be covered by uninsured/under-insured motorist coverage?

I agree, this is one of the best forums out there!

Best,
Dave

Hey Gabe,
Glad to hear you're still around!

Dave

Nissan used purpose-built hardware to identify the cylinders and make use of the 360 slots, and the MegaSquirt doesn't have this but does have code to use the AEM-style or DSM-style CAS. The MS3 uses a fast enough processor that it can get around the need for dedicated hardware, but right now using...

You're not the first to say "wretched 360/4 wheel and the optical sensor in the factory ka dizzy", but I've not heard anyone say what the problems are. Does anyone know, or have a link to information about problems with the stock CAS?

Thanks,
Dave

Yes, exactly. You're just relocating the pins from where they were in the connector defined by the 240sx ECU, to the Consult pin locations in the ECU connector for the Stanza ECU. Those wires then become the Consult connections you need in the CHECK connector. Then cut the 5 wires you need for Consu...
