Guaging interest on a BETTER THAN JWT Q45 ECU.

[elwesso]

Expect a week at least..... Remember that Robert is doing this for a hobby... He didnt quit his day job

[erbe]

I'm in

[chinaonnitrous]

Ooooooooooooh Big question

Nitrous? JWT has a nitrous modified ECU.....would there be an option for this also? I plan to run........a small shot. =)

[elwesso]

He said he could make them, but that would cost you extra... From what he said to me he cannot replicate the JWT nitrous ECU how they have it... he said he could build one and it wouldnt be too hard.

Are the successful one the A18-Axx-xxx p/n as opposed to the A18-Bxx-xxx p/n? seems like character 4 changed from 'A' to 'B' in the my'93 run.don't want to snag a 93 tcs box [b12-p74] just to find its the same deal as the '94/'95.

[DrewQ45]

Wess,

When I switched to a 93 TCU for first gear start, I noticed a harsh 1-2 shift under WOT. Many others with similar setup did too. It's a lot better with my new transmission, but still a source of worry for me. Is there any adjustment that can be done on the ECU to combat this?

I also have a few names for the ECU...

"Golden Tech ECU" or "Wess Tech ECU"... all you need are some stickers now.

[Raxephon]

If you decide to install the chipsocket from the getgo, ( for any upgrades that come along), then I'm definately in.(Even if it costs a lil more)

[rsiwicki]

Well...of course count me in :-) as it would not do my Q any justice not to after all the work done. Just keep coming up with new toys to give me another excuse to keep it....besides, I need another excuse to go to the 1/4 track. Have not been in 4+months which is a long time for me considering I was running every other weekend for a while.

A couple of things I will need are as follows:

1. Delete EGR sensor as my headers and EGR don't like each other causing the check engine light which gets tiresome except around xmas time as my dash is lighted up with a whole bunch of yellow lights

2. At what rpm does the program start? I remember the JWT starts at only 3,000rpms and above? Can we select a lower rpm (say 2,000) for the programing to start changing?

3. Why do I have to find a 90-93 TCS ECU for my 95 TCS car? What happens if I run a non-TCS ECU in my TCS equipped car? I hate my damn TCS..it works too damn good when it works and I have a stupid TCS malfunction light on all the time anyway because of some stupid sensor so it we could bypass TCS that would be great.

[elwesso]

Rob..... We can use your JWT... Since we can take that chip out, we can reprogram it... WE can reprogram any JWT ECU, youll just have to send us the entire thing... The only thing prohibiting us from redoing the 94 ECU is that they do not make a chip for that board... We have the capability to reprogram them, we just cannot because we cant get the chips..

We can delete the EGR with no problem...

The program starts at just below 2000 RPM... JWT ECU has extra richment below 2000 RPM, and we advanced the timing and stuff there...

I dont thikn we can totally disable the TCS system through the ECU but I will have to verify that with Robert... I said earlier that a non TCS ECU will work fine on a TCS cars, the lights will just be on.

If you decide to install the chipsocket from the getgo, ( for any upgrades that come along), then I'm definately in.(Even if it costs a lil more)

This is how we're installing them from the get go... All youll have to get is a chip puller, which are really cheap...

Drew, I dont think theres anyway that we can change the ECU to combat the harsh 1-2 shift. I'll verify

Jay I think your right.. it looks like we can only do 90-92 ones..... I've already emailed Robert a few of these questions that I cannot answer.

[elwesso]

OK ive figured out how we can tell the difference between the ECU

The easiest way to tell is to pull the lid off the ECU. If there is a second, upside down PC Board screwed under the cover, it CAN be modified. ECUs with only the main PC board cannot (yet) be done. The later ECUs should be able to be reprogrammed in a few weeks....

After we get the ECUs done, we will start working on a the TCU which shouldnt be complicated.

[rsiwicki]

Ahh very good...when I return from London I will send off my ECU as soon as I get my other car out of the shop as it is being worked on right now also and don't want to have two cars down and out.

[guadofreak]

So for my 94 TCS ECU, I need to find a 90-93 TCU ECU?

I WANT THIS LIKE A 12 year old wants a playboy mag.

I want to keep TCS, that is possible correct? I got confused so just please spell it out in plain english for me. I can find the ECU no problem as I am sure you have no extras if need be.

[franknitty69]

Wes,

I have a 95 w/active, traction control and a jwt ecu.

So to upgrade, i just need to send you the ecu and you'll reprgram the chip with new data? And everything will work as is currently (tcs, active, etc.)?

[Q451990]

Would it be an option to just buy the chip and socket from you and solder it in myself? Robert will be able to judge my soldering abilities and advise on if this is a good idea as soon as he receives my consult interface...

I think we could do that, but pricing may change, ill have to ask...

Correct..... Send us the ECU and we'll simply install our stuff, much like one would upgrade operating systems...

Yes, youll need to find a 90-93 TCS ECU, and the TCS will wokr just fine.....

We have 2 extra TCS ECU if you cant find it, the TCS ECU are much harder to find than regular ECU

[guadofreak]

Sent email. Gonna do a once over for all the places near me and my contacts just to see if i could possibly find one.

[chinaonnitrous]

so when can I send mine out? =P

[RobertsnewQ]

Glad there's such a good response. I've been corresponding with Wes for about 3 months now, and he knows the details pretty well. He covered the basics.

The A18-BXXXXX ECUs have a different processor, and while they CAN be chipped, I'm not set up do do them (yet). They will require a daughterboard which will add a bit to the price. I'll let everyone know as soon as possible.

My late '93 had the 8-bit (good) ECU, so I think all 93s will work.

If you want to desolder and solder the chip yourself I'd be happy to send a chip and socket to you. You could even take it to a radio repair place to have it installed if you want - it isn't hard.

I think for most ECU's I'd leave the rev limiter at 7200, but if you want the crazy "Wes Special" lemme know and I can set it at 7400.

I did add timing below 2000 RPM, which adds to the snappy around town feeling. Fueling is pretty good down there - it only gets nasty rich up top. The high end timing is close to JWT (I actually took out some in a few spots so it works better with crappy CA gas). Let me know if you want it optimized for 91 or 93 octane gas.

The EGR can be disabled. If you live in a state with dyno smog testing, the EGR removal will cause failure of the test, so let me know if you want it left in or removed.

In general the program won't have much effect on emissions other than that. The top end/midrange is a BIT leaner than stock, which COULD contribute to the cats wearing out faster than original, but no guarantees either way.

I can put a non-TCS program on a TCS board, so you will never get a warning message or anything if you use it with a non-TCS car. If you use it on a TCS car I have no idea what will happen so I wouldn't reccommend it. Same goes for Active (its the same board as std) - you can use it in either.

I'll be doing some dyno testing in the near future and I'll post results.

[elwesso]

Basically what we're getting here is we're not trying to rip anybody off.....

Also, like Robert said, the ECU program that most people get wll be slightly safer than the one I have... Please notify me if you want the more advanced program, but I only recommend this on cars with outstanding mainteance, with many new parts... The 7200 vs 7400 really isnt that big of a deal and I shift at 7200 most the time anyway... My ECU is about as maxxed out as one can get, the ECU most of you willbe recieving will be slightly less.

Bottoml line its probably best one gets the 90-93 ECU as they are easier to modify...

If you do desolder the stuff yourself, I think its pretty safe to say your on your own....

[rsiwicki]

I am now getting my hopes up of finally breaking the 14.0 sec 1/4mile barrier. Need to slap back on my 15" BBS and have some cool Miami weather in January and then off to the track to see if I can squeeze off another 0.25secs. I predict a [email protected] would finally come full circle as I have always had the goal to break the 14.0sec barrier when I started my maddness about 2 years ago in modding my car.

[elwesso]

Rob Ive been watching on ebay and it looks like you can get some drag orientied radials in 235-60-15...

[zinkie13]

I don't know if this is beyond your knowledge but I think there would be a huge market if you could develop and upgrade for the y33. As far as I know the only y33 chip we can get is offered by Impul costs around 1000, not including shipping from Japan. I guess we could also get it modifed by JET but i'm not sure I would trust whatever generic programming they use.

[elwesso]

Im sure robert would be willing to develop one if someone would send him a donor ECU.

[chinaonnitrous]

For what its worth, the JET ecus have been the butt end of every ECU joke on our maxima.org forum..................*shrug*

[Ozzie]

The impul ECU should be about equivalent to this ECU... We had a JDM ECU and we compared it to the US ECU and made some tweaks that way.....

Thanks for the info.....

I still think this is a damn cheap upgrade for a stock ECU.

Any idea on price to modify the TCU?(If it's possible, of course!)As my Q seems to start in second, unless I manually shift, or REALLY put my foot into it.Thanks to Robert and Wes for making this offer to other NICO members....I am yet to find another group of people who are so helpful and sharing on the net...

And I quite enjoyed the video too Here it is again, incase anyone missed it!

http://q45.spilky.com/Q/102-0212_MVI.AVI

[erbe]

Is it possible to get the program by mail?A friend of me can burn it to the eprom.I'll pay ofcourse

[elwesso]

ill take some more videos this week.....

TCU's will come when the ECU project is finalized, we are still developing stuff.

[q45_owner]

ECU takes about 15 mins to pull... really easy, just a screwdriver and a 10mm wrench....

Once I get my new EPROM and test it, we'll be good... Plan is to commence before christmas.

All I have to do is pry the panel out with the screw driver? Just making sure because I don't know whats behind the carpet covering it and I don't want to to break the plastic. That time frame sounds good to me!

[zinkie13]

I could probably send mine after christmas break as long as it wouldn't be gone for more than a couple weeks

[RobertsnewQ]

If you have a daily driver and you need something right away I can send a reprogrammed ECU on the honor system until you return your core.
