I also posted this in the Q45 forum...

I know some people are really looking for NICO ECU's... Well, I think im getting a little closer to getting my 94 boards done, so I'd like to get some 90-93 ECU's out of the way..

cost is $250 for a 2 way 90-93 NICO ECU

THIS ONLY APPLIES TO THE 8 BIT 90-93 ECU'S. I CANNOT DO ANY 94+ ECU

However, that does not mean 94-95 owners are out of luck. the ECU's are all cross compatible with a few minor differences.... Ive run a 91 Q ECU in my 94 for the past year or so and its worked great...

What im doing is a run of 2 way switchers for 90-93 ECU.. I'll probably program them with stage II and stage III unless someone else wants a custom one (not a big deal to make)....

I do NOT HAVE any CORES, so any ECU's that are getting programmed need to be sent to me for programming... All the cores I have I believe are 94 ECUs but I'll double check.

Next week is my break so I dont have anything to do, so hit me up if you want an ECU done!!!!!

I'll look forward to you getting the 94-95 ECUs done. I've got 2 ECUs and one happens to be a 94 and one is a 95.

For myself, and anyone else who may not know, what exactly do I get for my $250? remap, rechart the air/fuel,really curious? What other mods help, and since i already cut my egr off the back of the runner, I need to have the ecu dealt with. Thanx

I've been informed that you will NOT throw a code for the EGR if you have everything removed as long as you leave the solenoid connected. I pulled that connector through the dash and I'll just leave it connected under there.

These ECUs are supposed to add a very noticeable amount of power. Can't wait to get my hands on one.

You get a completely revised map that was dyno tuned from scratch for a VH45DE. Gets a new AF and timing map... You get about 10HP MORE over JWT's program.

It was tuned using 91 octane fuel here in the states...

I can turn off the EGR fairly easily I believe..

Im not sure what other information you are looking for?

Perana... I could do that but im not sure I could set it up for a switcher going that route, let me confirm it for you. I dont ahve anything against sending you a chip and socket, just there wont be any technical support available regarding its installation.

thanx Wes, that is about what I was looking for info wise. What is stage III? does it require 93,98? With a 5spd, I assume this would really help to get this motor to really come alive. How hard will it be to get one in a month or so? If i sell my 74 Jimmy this weekend, i may get one sooner.

shouldnt be a big deal, i just want to do as many at once as possible since im going to give them to a friend of mine to do the soldering..

Stage II is a bit safer than stage III. Stage III does things like ignore the KS, o2 sensors, etc at high load.. It probably gives 5-10HP over stage II...

Sounds good. So on three, what does it run like when not at WOT? Does it just open the injectors and flood it, how is the AFR? What does it do to the timing? Just really interested, and having seen these questions/answers in my search. thanx

The stage III program runs great... In fact, I havent switched it off stage III in the last year. I did for a week or 2 just to see if I could tell much of a difference, and I could...

The only difference really is the lack of "safety equipment" at high loads, other than that its roughly the same.

Send me an email.. I'll send you my addy and you send me an ECU with some form of payment. I can do paypal or money orders.

So what are these "safety equipment" settings? I'm a little concerned that when I run my car at a track event (i.e. 1/2 hr lapping sessions (5/day) and time attacks), I maybe running a little too much on the edge. Certainly longer and harder then any Q45 will be used for. I realize that several 240SX guys are drifting these VH45DE cars, but how long does one of their runs last? 3 min? Will I be running a risk of "holing" a piston or burning out valves if I run it very hard for these time frames? I have seen allot of "tuned" engines run very fast times in the 1/4 mile for years, but when you run them hard for a 1/2hr or more on a track, they eat themselves up. I really would like to run this ECU, but I would like to know the risks up front.

I wouldnt be concerned about it. Ive ran my Q harder than 95% of most people would and I leave it on stage III all the time...

Its not a ragged edge sorta thing... Stage II has, maybe 10% safety left in it where stage III may only have like 5-7%.. Still enough leeway so you wont blow your stuff up...

Worst case, you can lose the 8-10HP and run stage II all the time. I dont sell stage III alone so you can always switch it down a notch if you have to... If on stage II you start detonating, the KS will pick it up and fix the problem..

I'm sold. The cars all apart since I'm doing body work prior to painting, so the ECU isn't really needed Were do I ship to? How would you like the payments arranged?Let me know.Thanks

I had an ECU with Nissan part number 23710 61U00, mfg part number A18-000 P00, 0711. It was supposedly a 93 JDM ECU. This number is very similar to yours and the 12 instead of the 00 can easily just be additional features (such as traction control or actives susp or something) or a later firmware rev for the same year. I definitely think ours are not USDM part numbers. I checked the canonical list at http://jimwolftechnology.com/wolfpdf/ECU-ID.PDF . It's not in there, which means they've never seen it (or they didn't update their chart for a long time).

I sent my ECU to Wes, so I'll let him comment on whether or not this type of ECU can be modded. If it doesn't work out, I'll send him the 90 USDM one that is installed and running in the car now.

Throw me an email... Since your not in the US im going to have to charge a little extra for shipping...

JWT's list is anything from comprehensive. IF you take the top of fthe ECU and take a picture I can tell you if its an early or a late ECU.

My VH45 engine # is 007757, and the car was an early 90 build date.

The #'s here on the ECM, are a big fat 01 and A18-A21 P01 9Y30Pics to come in the morning

Hey wes,

Could you do a ecu with one tune for stock injectors and boost, and the other tune for 550cc and boost?

No. In order to tune it right, you have to tune it on the car. Changing the K value in the injector thing doesnt really make it work right.
