Sorry if this is another bunk ebay add but I read thru this one and this chip plugs into the actual ecu rather than maf sensor. Its not a resistor. Claims to peform the same functions as JWT/jet upgrade. New rev limit, top speed, fuel and map timming.... Its price is cheap and thats what scares me please check it out and give an honest opinion.
I wish someone from here would go for it. I really want too see if this tune is any good. If it's good it would save me tons even after the cost of converting my car to obd1 its still cheaper then jwt.
I think I might try it out. Hell its 40$ and they make it sound like its pretty easy to install and take out if needed. (like for smog testing) I dont know gotta sleep on it. I wish there were install instructions online just so I could see what im getting into before I commit to buying it
First off, the Altima ECU has a soldered-in ROM chip which is of the large-scale PLCC packaging type. The picture on their ad is of a simple memory chip.
Take a very good look inside my ECU and tell me where that chip will install into,
By the way, the Altima ECU ROM is called a Versatile ROM and it is the big one to the topmost right side of the picture, it has a sticky label on it. The Versatile ROM has a lot more internals than that of a simple memory chip.
The only way I could see that chip getting installed is by putting it into a daughterboard. And if that is the case, the installation require electronics soldering skills, not easy for the average Joe Blow.
Here is a picture directly from their own e-Bay site,
Get them to send you the exact installation instructions for you to review. Better yet, have them give you three eBay users that has installed it on their Altima (we can then send them direct eBay messages to verify legitimacy.) Post that information here. And we can tell you in a heartbeat if this is legit enough to work. If they balk at sending you the installation instructions or eBay users, then buyer beware.
UPDATE:
Here is yet another link from them for your enjoyment,
So with the links jserrano posted it looks like his ecu needs a motherboard. It would still work. I know I would need help. If the ecu matches there first example then we are in buisness and it shouldnt be hard. Ill take it to a tv repair store and have them take out the old chip and put in a sproket so I can take it on and off when i desire. Dosent seen that hard just need a good solderer.
This topic was discussed a year ago.
I emailed this guy last year and he told me that I'd need a daughter board to make it work with Altima. I'm not sure but it will cost you around $50 or more.
Yeah, and he also suggests to get it soldered by someone in electronics repair shop ($10).
I don't see the reason why it shouldn't work but I didn't want to be the guinea pig.
it seems you need a daughterboard... if you check the ECU forums a month or two ago i was in contact with a guy about these chips for our cars. they are supposedly good chips (altho i havent looked at zilvia in a while). he said that he would do everything for my ecu for $100 plus me shipping my ecu out to him. it seems pretty legit to me, altho you need some soldering skills and a daughterboard for this to work i bet.
my guess is that the pic he posted was just for looksies... he seemed pretty credible when i talked to him a few months ago
