de computer on an e

[acrazyjohnny]

can i use the de computer on the e with out having any problems i want to tune my e computer but right now i have a de computer lying around and wanted to know if this would be safe and if it would le me rev to 7000 on a stock sohc motor and if its safe to take it there

[S13 240SX]

dude its not an sr20.. don't rev the stock sohc to 7 grand.

i hat ethe sr there a kid in my town who thinks hes the **** b/c he has on im going to spank his *** and i qoute from his mouth "that pos old *** truck motor that only revs to 6000rpm and doesnt have **** on my sr" so i got a surprise for him its called nitrous and im gonna whoop his *** with it just to show him wat my old *** ka has

The ka24de ecu requires a daughterboard and the ka24e ecu does not, ka24e ecu is cheaper and easier to tune.

In order to run the ecu you would have to trick the knock sensor and switch the IAT sensor to a ka24de type egr sensor, or set it up with resistor.

Also the ka24de ecu will need major changes in the ignition map, its way too retarded for an E.

You sound just as bad as that kid in your town... read, learn, grow - pbs style

Hey DeviousKA,

Since we are talking about KA24DE ECU's here, I have a question for you. I printed out a list of all the Nissan KA ECU's that Nissan has used off the hybridKA.com website and there are only two versions listed for the 5 spd fed emission '91-'94 240SX, those two being the A11-B44-G07 (for '91 models only) and the A11-B44-G70 (for '91-'94 models). I have one of each in hand and was wondering which one has more aggressive programming for use in my KA24DE swap into my 720 pickup? (or are they really just the same?). I kind of feel that the G70 version must have come out slightly later in the '91 model year and probably has a slightly updated programming, but I don't know for sure?

i reved my sohc to 7gran all the time and it pulled the whole way.. then agin, it wasn't stock

[deviousKA]

The G07 (53F00) ecu and the G70 (53F01) ecu have very minute differences.

The later model 53F01 ecu has extended closed loop and knock detection areas. This is very minor, it only amounts to 5 or 6 cells where it would be in closed loop or knock detection more than the 53F00.

There is an area around 2400 rpm and medium load that the 53F01 is set just a tad leaner, not really of any significance.

You wont be able to tell the difference between the two ecus, try the early one and see how you like it.

I hate knock detection and closed loop anyways, it only retards timing on cheaper less expensive fuels....... Ecu tunes are more aggressive without them.

[deviousKA]

Yep, and that is an easy thing to do within the ROM.

[Bigvinnie]

Devious, I've been wanting to try the Jaun Willy tune. Supposedly it has some closed loop disabled and knock sensor cutoff(for better consistancy and timing advancement). It was noted that this tune makes some good power on a bone stock KA. How dangerous is it to run that tune on standard Compression and California 91 octane. I am under the assumption that it would be fine since cali fuel is 2% oxygenated and mixed with 5% ethanol. Plus I live in the Bay Area the air out here is nice....

[deviousKA]

The JWT tune has minor changes to the fuel/timing maps, you will be plenty safe with standard compression ratio and 91 pump fuel.

Probably wouldnt have any issues with 89 octane either, depending on base timing.

The JWT tune has minor changes to the fuel/timing maps, you will be plenty safe with standard compression ratio and 91 pump fuel.

When did JWT make this tune (Juan Willy)? I am trying to copy the power output that this 240sx made back in 2001 with ecu tune (JWT), 104Octane, underdrive pulley, header and 3"cat back (169whp,170ft-lbs torque). JWT no longer does this tune, for what reasons I don't know. But it put down some serious HP to the wheels without internal modifying.If I disable the closed loop more to make it more (consistent in the map) would it be possible to use 91 octane and get the same results than using the 104octane in this dyno.I'm looking to achieving the same power utilizing a lower grade fuel basically.

[deviousKA]

May be the same tune, but I am not sure.

Get some A/F logs on your current setup and go from there. Make sure that when you do, you have just removed your battery cable and the ecu is free of codes throughout the run(s), especially any knock code.

Timing is where you are going to pick up the most gains. You can go with a general map modification that will provide good initial results, but realistically the timing should be perfected over a period of time as you continue to modify and change your engine. Or as always, by monitoring torque output on a dyno in relation to timing advance with detonation detection, once you are satisfied with your engine configuration.

You have california model car? What are the numbers off of your ecu lid?

[Bigvinnie]

You have california model car? What are the numbers off of your ecu lid?

Yes I have a Cali model car. Number listed on the top of the lid is 92, last I could recall. I understand that disabling the closed loop will cause problems and possibly throw codes. I've been told that I will probably need a FED ecu.

I was wondering if I had a ka-e ecu modified if I could use it in a de. Modifying the e ecu just seems a lot easier. Are the harnesses similar btwn these ecu's. What all would be physically involved in getting this to work.
