Chip?
A fellow 'car guy' and friend of mine emailed me this link. He says he has installed similar chips in a 1989 BMW 325 and Audi of a similar vintage with positive results.
Ebay Motors item # 200249673339
Thoughts?
Unless it turns out to be absolute BS I think I will order one since the price is so minimal.

the only thing that bugs me about it is that usually people lean it out for better top end power on n/a (ie, less fuel), but they say
These chips will increase the fuel delivery at the injectors and advance the ignition timing accordingly, in order to produce optimum power.

i would rather go mechanically instead of computerized by increasing a bit valve overlapping and advancing a lil ignition timing...and it comes to the same point maybe better than that....
other way around horse gonna run faster.....

The VG and VE ecus are completely different design and layout. That's why it's so effin hard to chip the VE. the VG is much easier to work with.
Chipping any engine is a good way to add power over the stock programming. cams and such will help too, but you're still limited to the stock programming either way. (same can be said for cams as well, but you get my point.)

Ready, here we go..
The seller states he has a EPROM chip for the VE30DE ecu, ok...we all now know this is a false false false statement. So in turn, why would you believe this guys product for the vg ecu will actually work? I think i will pass.

Ok guys, i know i don't have matt's smarts here, but think about this a minute without thoughts of ear bleeding horsepower from your vg's in your heads..

being that they claim to have an actual shop, that should be no problem for them to actually crack open a VE ECU for us, and show us the chip installed, etc.

Dear drape123,
hello....can u acutally show us the chip soldered in the ECU and if u can then can u show us the OUTPUT of the ECU...cuz 1989-1994 maximas have 2 ECU one from VG30DE AND OTHER FROM VE30DE...thanks..

Item and user details
and this is wat i got back from him...
Dear burhangondal,
yes it is th e chip with the sticker on it
- drape123
Did this answer your question? If not, let the seller know.
EDIT: NO OFFENCE BUT i dont think so if he even know wat he is selling

Hello, I just had a few questions about the eprom chip you are selling for 1990 through 1996 Nissan Maximas. It has been brought to my attention that the 1992-1994 SE's do not even have an eprom chip on the ECU, could you please explain to me in further detail where, and how this chip is connected to the ECU if one of the models you're advertising for isn't even applicable? 1989-1994 GXE Maxima's with the single overhead cam VG30E, do have a five mode ECU system, but I have yet to see any kind of chip designed for that ECU in the twenty year history the car has been out. Do you have any detailed pictures, a phone number, or an email where we can continue to talk so I can get more information on this product? Also, what is the name of your shop? Thanks. Taylor.
hello, please check out www.e-mance.com/ecu tell me which ecu you have.. we make a few daughterboards for different nissan ecus the early 90 maximas we use a special daughterboard which allows us to tune these ecus.. check the website and tell me which ecu you have

IMO its irrelevant whats inside, the FSM details all the input/output logic used by the ECU to make its decisions.
When I've "pondered" reprogramming the VE ECU, my thoughts have always wandered to getting a few voltage sensors/senders that interface with USB, connecting them to a ECU harness, and then programming all the logic on the laptop. I do have enough knowhow to do this, but I would have to be mighty bored to follow through.

I have a broken VE ECU next to my desk. I'll bust it open and post some pics.

Multiple 2-D arrays of value pairs? Not a big deal. Most of what I do at work is scientific and computational programming, as I said I have the knowhow and its the type of stuff I deal with on a regular basis.

if this chip for the VE turns out not to work, i guess it's back to square one, and by square one, i mean Hadman's consult port nistune thingy.

I think it would be cheaper to just buy a programmable ECU and tune that yourself instead. I had also contemplated using a Motorola 68EC series microcontroller but after summing up a rough design and adding up the potential costs including the R&D, it was cheaper (and better) for me to go straight to the MoTeC M800 instead. More so because my software programming skills suck, as opposed to my hardware programming skills.

JWT has spend thousands of hrs doing this for yrs on the R&D side b4 coming up with his product...Why not save some time, frustration, and money and buy a JWT reflashed ECU and call it the day. Tuning drivibility/power isn't something you learn overnight in your garage....
