99 ecu help

[98gstblackwidow]

So long story short, I ordered a plastic case flash ecu from dsmchips.com with ceddymods v1.9c for my 99 GST and got a 4k rev limiter launch control and 5500rpm nlts limiter.
My problem is that when the ecu was first hooked up in the car my car would only rev to 5500rpm (over 7mph). My launch control works fine while I'm sitting still (under 7mph). So I figured I needed to hook up my nlts wire for everything to work fine.

Well I hooked everything up according to the ecm page/link and still got the same results. My cruise control works and when I press the pedal in slightly it triggers the switch and my cruise will go off, so I know that part is good.

If there is something I am missing or doing incorrectly please just let me know, thank you very much and sorry if this is a noob question. I just ordered openport 2.0 to help resolve the situation but am currently at a stand still with the car.
I have my stock ecu I can put back in for the time being but this one is fine just only revs to 5500rpm.

I also have pictures of how I have everything hooked up if that would help you out.

Ok according to Ceddymods thread you should be wiring into pin 44. So when the clutch is pressed pin 44 will go to ground and then the ECU will drop RPMs to 5500.

Check to see if you have anything in pin 44 that is grounded.

What you referenced is ECM link which must do it different.

Ok, so I run the long red wire into pin #44 instead of into #91? Hook 91 back up how it was and my 44 pin on my harness is empty, just add a pin connector and put the red wire into it and it should work fine after that?

*UPDATE*
I ran the red long wire to pin #44 and hooked the white wire into the green wire going into the safety switch (the switch needed to push the clutch pedal in and start) not the cruise switch (how I had it before in the pics) and the yellow wire going away from safety switch. My nlts is now disabled because the car will rev to 8k.

Has anyone successfully added nlts on a 98-99 car and ecu and got it to work? If so could you please take pics of how yours is setup. Thank you.

Does anybody have any idea how this wire goes? I know most people have link but somebody has to know. I spent all day yesterday looking on the internet and calling around local shops. I either heard/seen how to hook it up for link or nobody knew.

Sounds like you need to check your clutch switch again. It does go to pin #91. Here are the places where you should have been looking for your answers:

CeddyMod v1

Newest release is here -> http://ceddy.us/?page_id=16

Please use this thread for discussion about CeddyMods only,
other DSM EcuFlash discussion should be here -> http://www.dsmtuners.com/forums/tuning-engine-management/338754-first-flashed-dsm-ecu-98-99-flashing-faq.html


"What is CeddyMod?"

CeddyMod is a bundle of code modifications for the DSM flashable ecus.
It is modeled after the famous TephraMods for the evo ecus, and tries to use similar units as used in the evo code changes, so Loggers and other tools will remain compatible.


"What code has been added so far?"

Launch Control

• Stationary RevLimiter

• RevLimiter Switch Speed

• AntiLag

• NLTS

Launch Control consists of a Stationary RevLimiter(2-Step, StutterBox) that is enabled when stationary and at low speeds.

Once the RevLimiter Switch Speed is exceeded the normal rev-limiter takes over. A good setting for this is half way threw first gear, or what best suits your launch style.

AntiLag is added to help build boost when using the Stationary RevLimiter. It does this by retarding ignition timing, which produces more hot unburnt gases, that spools the turbine faster. The lower the retard the more boost will be produced, but EGTs will greatly increase. The AntiLag Start RPM should be set to a few hundred rpm lower then the Stationary RevLimit, at the point the rpms bounce down to off the Stationary Limiter. Your rpms will will climb slowly when the timing is retarded, so for a quick, crisp launch control antilag should only be enabled for a small rpm range.

No Lift To Shift, NLTS is a mod that allows you to keep the throttle floored while shifting. It lowers the revlimit to a set point when the clutch is engaged. NLTS is enabled after the RevLimiter Switch Speed is exceeded. This mod requires adding a wire from the clutch pedal switch to ecu pin 91(Park/Neutral Position Switch).


Logging and Map Mods

• CEL on Knock

• 1Byte Load

• Airflow Calculations

• Map Switching

CEL on Knock will light the CEL once a certain knock count is exceeded. If the CEL is already lit from an OBD code it will flash the CEL off. This gives you a quick indication when you are knocking.

The mitsubishi loggable Load dilemma. The MUT protocol used by mitsu ecus, uses one byte(0-255) to transfer information. This causes the Load item to max out at 160 when logging, Loads higher then 160 couldn't be logged. The evo guys developed the 2Byte Load, this used two bytes to transfer info, this allowed any Load to be logged but slows logging because twice as many bytes are transferred. The 2Byte Load also suffers from a byte mismatch problem around the 160 Load point, this cause spikes in your graphs and bad info near the 160 Load point. Later on the 1Byte Load was developed, this uses a multiplier to allow the logging of higher Loads. The multiplier is editable to allow the best resolution with the highest load you need to log. For example 255x1.2=306 Load, 255x1.4=357 Load, etc. The 1.2 multiplier is a good starting point, because it is near the 310 Load limit of the 2G MAF.

The OBD2 code includes a set of Airflow Calculations that will calculate your airflow in lb/min or gm/sec. This mod adds these calculation to the MUT protocol and allows you to log your airflow in easier to understand units. These airflow numbers are useful if you want to plot your location on a compressor map, etc.

The DSM ROMs have a second set of Timing and Fuel maps that are unused. Map Switching allows you to easily switch between these two sets of maps. You can have a pump gas tune on one set of maps and a race gas tune on the other.


"What is the Current Version?"

CeddyMod is at 1.4 beta

Stationary RevLimiter - Tested Good
RevLimiter Switch Speed - Tested Good
AntiLag - Currently Limited to a max of -5 degrees
NLTS - Not Coded
CEL on Knock - Tested Good
1Byte Load - Not Coded
Airflow Calculations - Not Coded
Map Switching - Not Tested Yet

If you do not understand something, do not flash your ecu.
This is a Beta release and everything hasn't been tested, care should be taken when using it.
I take no responsibility for any damage caused. If you blow up your motor or brick your ecu, thats all on you.
AntiLag and NLTS are some "hardcore" mods, if you haven't used them before, research the damage they can cause.


"CeddyMods is Donationware"

This means you pay whatever you think its worth.
Making definitions and writing new code is very time consuming.
If I get support from the users, I will continue writing new code and making it available to the public.
Hopefully together we can develop the best engine management system available for the DSM.

Sounds like you need to check your clutch switch again. It does go to pin #91.

Checked the switch 5 different times and replaced it with switches out of my 98 GST Spyder and my 99 GSX and 95 TSi's. So a total of 4 other switches have been used. I highly doubt I could have 5 bad switches.

I've read all the pages you linked btw.

So in my pics the wires are hooked up correctly? Why does ceddy say to run it to pin 91 on his page but is telling this guy to run it to pin 44 on this page: http://www.dsmtuners.com/forums/tuning-engine-management/377189-nlts.html#post152277620

 

[delta448]

Ok pin #44. So it was only pin #91 on the older versions of his ROMs? Wonder why it changed.

Do you have a multimeter or electrical test light?

 

[98gstblackwidow]

I have both a multimeter and test light and have tested the circuit on both setups. On pin 91 and 44, both are reading the same as when its hooked up the stock way without the nlts wire added (only pin 91 since my 44 was empty) I think I have tried about 12 different ways now with the wiring.

I even tried hooking it up to the safety switch, the plug most people undo to start the car without pushing in the clutch pedal. And when I hooked it up on the green wire there and ran it to pin 91 I still hit 5500, but when I ran it to pin 44 I could hit my 8k rev limiter. Not sure if that's a step in the right direction or what.
