okay, thread title you must be like, wth is he talking about. anyways, i learned this info from a friend. he has a 99 se-l, and took a 95 g20 ecu and put it in his sentra. worked very nicely and bumped his rev limiter from 6400 rpm to 7100 rpm. this was found out by accident or something from some guy on the b14 or se-r forums. anyways, jus curious if anyone tried this on a 2k maxima... or something. Please don't flame... just curious.

never hurts to ask (most of the time)

 

No, they have different harnesses. But you can cut and splice about 70-80 wires and it will work.

 

nice... im curious though, tilley is the one who put the 4th gen ecu with the 3.5, is that what he pretty much did - splice a bunch of wires?

 

Well, I am pretty sure he spliced the wires in hte engine bay, which is easier. I am pretty sure he had hte entire 4th gen harness in the engine bay.

I could put he DE-K in teh 4th gen and use the 4th gen ecu and wireing harness. But for you it is a little harder. You can swap the entire engine harness or you can just cut and reconnect where the ecu is.

 

Kevlo what about using a 5th gen ECU on a 4th gen (99 cali) with a DEK manifold?

that way you can get a raised rev limiter on the 5th gen ECU (obd-II) to take advantage of the DEK's top end, instead of going with a modified 95-6 (obd-I and check engine light) since any 97-99 4th Gen is out of luck on modified ECUs

 

00 ECU redline is 6400. 4th gen is 6550.

Better to install DEK manifold and use an RPM switch to activate it at 4600.

 

No its not, its 6550 just like yours.

 

Wheren't 95-96 ECU's OBDII?

 

my stock redline is 6700 rpm, at least thats what the tach says.

 

ALL 95+ Maximas are ODB2. All of them. 95s have the connection on the passenger side.

95-96s have the best ECU modding options at the moment. The only way to get a raised rev limiter through a reprogrammed ECU. 97-98 can use a 95-96 with only a CEL. I think JWT and maybe TS can get some kind of ECU to work with the 99s. Check with them.

Since you have a 2000, you would have to either use a 4th gen which would be easier or use a 5.5 gen which is for a different engine and I am not sure if it would work. I think TS is working on getting the 5th gen ECU to work but I am not positive on the status of that project.

in short: No you cannot swap another ECU in easily nor would you get a performance gain unless it was reprogrammed.

 

Are those gauges out of a 02-03 SE or are those stock for 00-01? Either way the REAL (not what is on the tach) stock redline on all VQ30 (if not VQ35 too) is 6550 rpm.

 

I believe JWT did this many years ago... They used a '96 Maxima ECU in a '00 turboed maxima project they were working on. The turbo kit wasn't any good and never made it into production. Reason you could tell it was a '96 ECU there wasn't a DEK switchover, the manifold stayed closed all the time which hindered its top end performance.

 

thats out of a 01. It doesn't matter to me really cause the TS ecu allows me to rev to 7100 rpm anyways. The ecu has been released for 01 5spds already but hasn't been listed on the site yet.

 

People told me that on their OBDII readers it said 6400....

 

Sometimes my rev limiter cuts the fun at 6100 rpm. If i raise the rpms slow I can get to maybe 6400. It's pissing me off. (2000 maxima engine) I want to get to the 6550 rpm. I have a CEL and it may be affecting the cut off?

 

For clarification...95/96 maximas are OBD 1 not 2, 97s and up are OBD II

 

From 1996 on ALL new cars sold in the USA had to be ODB2 compliant. The 95 max has an ODB2 connection but it does not have the extra emissions, sensors, etc. and the plug is behind the passenger ECU panel.

 

Yes. I have a '96 and it is OBDII. I have used an inexpensive converter ($50) and a laptop to connect to the ECU. Kind of fun to pull the codes and get real time data.

What I'd really like is the Nissan Consult hardware and software. Too bad that is so expensive.

 

Thaniel,
a Maxima engine in an RX-7. thats just plain awesome. any info on it congrats

 

Wrong wrong wrong.
