Ummm... How can i socket my ECU when it looks like this???

[driftin8ez]

Well i got my mine's tube chip in the mail today and i was ready to install it when I found something very interesting inside my ecu. It looks like some jdm bees left some JDM honey all over my eprom. The **** is hard as a rock.

So it made me wonder what the heck. My ecu has already been chipped??? The outside cover has a sticker that says APP and above it, it says aviation performance products do i do now?

I included picture urls because the pictures are a bit big and didn't feel like resizing them.

geez, those are terrible pics, is that a charcoal rubbing or was your camera drunk? APP makes brake lines not ROM chips so I doubt anything has been done to it. I am not burner so I am not 100% sure but I think you have to unsocket the stock chip and install a docking port (not sure what it's actually called) so you can pop the chip in and out without soldering it in each time.

Drunkin' camera pics indeed, but you get the idea. However that yellow honey looking stuff is preventing me from removing the chip you see, It's underneath that and i doubt i can remove that without destroying the whole ecu. Also i fully understand what is involved in socketing/chipping the ecu i just cant get the old eprom chip out.

Here is an example of what a stock ecu should look like:



And another picture of mine to compare:

Stay in a holding pattern until some more members can see this thread. We have a few very knowledgeable ROM-ninjas who should be able to walk you though it.

[r34 gtr]

you're pwnd. find another ecu.

[driftin8ez]

yep that what i thought. What's going rate on a CA ecu these days?

[The_Chosen_One]

looks like APP dont want you to change yo **** LOL

[AWDB12wagon]

Is that stuff really hard? Maybe you an chip it off...or heat it up with a hair dryer...

[ca18det240hatch]

u have to use a chemical. you can get it at electronics stores, it smells like oranges, usually used to dissolve the glue that they put under chips to keep them from lifting. works good for that purpose, pretty sure it should be able to melt that glue. That ecu is usally a trick that MINES uses to prevent tampering.

good luck

[c-rad]

I dont think that stuff is coming off... its hard as hell epoxy. But like others said, its to prevent someone from taking the chip out and copying the code off it.

[driftin8ez]

I bought a mine's chip off ebay to soldier in. Is it possible i already have a mine's ecu? I remeber seeing a picture of the inside of a mine's ecu and the epoxy looked similar. Anyone want to trade chipped ecu for a stock one? If the ecu is already chipped then the fuel maps should be updated for at least 15psi and better fuel/timing maps Right?

[ca18det240hatch]

why cant you be in calgary

i need a chipped ecu sooo bad....

when im driving, my speed cut randomly kicks in after 140km/hr just for fun. heres the kicker, my rev speed meter, for some reason doesnt see my speed, but my speedometer does...and still the ecu is saying it doesnt see my speed so its gonna speed cut randomly....dunno.

Can you still get to the screws to get the board out?Ryan

[driftin8ez]

Screws I can get to the front and back of the pcb however ever if i desoldier the eprom it will never come out from all that epoxy. I have a new idea anyway. I'm going to keep my ecu with the chip that I'm assuming is a stage 1 chip for Intake/exhaust/boost. It runs on the stock injectors and maf so it can't really be much more. Then I'm going to pick up a greddy emanage and update it for my j30 maf. This will be much better because if i ever want to get dsm 440's i can just update it through the emanage and away i go. Instead of having flash a new chip and all that jazz. So to make a long story short I'm going to sell my mine's tune chip if anyone wants it. It's a Mine's tune with updates for fueling/timing, up to 17psi of boost, J30 (N60) Maf, and stock injectors. I got it for $65 so make me an offer if you want it [email protected]

You shure its not the N62 MAF? I dont think the J30 came with an N60 MAF. So the ECU is currently programed for stock injectors, MAF (N60 or N62) and cleaned up timing a little?

Yep timing and fueling are rescaled to run higher boost safer. Also, Yep it is an N60 MAF i have it sitting next to me right now. The j30 and maxima's with the VG came with an N60 maf. The 300zx's turbo or N/A both came with the bigger N62 MAF. The Z maf can supprt up to 500hp or something crazy high for our little CA's, The J30 (N60) Maf tops out at about 310hp which will never been seen by most ca's. I saw it to be much more fitting and far cheaper than an N62 maf. Also when i talked to speedlab I told them to tune it for a N60 maf regardless of what car it came from, That is the MAF that it is programmed for.

Edit: With further research J30's came with the N62 maf for like 2 years then they switched to the Maxima's N60 MAF, however this chip is tuned for the N60 maf. Which IMO is more than enough for most.

What do you guys think? Would it be possible to take a dremel and cut off the epoxy. I would obviously not be able to save the chip but would i be able to salvage the board?

Cut your losses and sell the ecu on ebay as a stage 1 ecu, then use that money to buy an OEM ecu....OR trade it to someone on here for their stocker. You'll end up messing something else up on the board (resistor, capacitor, circuit, cable, etc) and then your stage 1 ecu will be worth nothing.

[johngriff]

LOL.

You bought a mines chip by itself?

No You Did Not.

Mines Solders their chips in, then covers them in that sealant, so people arent doing, what you are doing.

Look at that sealant in the light, can you see a RED sticker ontop of the chip? If so, more than likely it is a mines ecu.

[driftin8ez]

i know it's not a legit Mine's chip but it has the mine's tune on it.

[BEST1TUNING.COM]

Its not coming out without damaging the board unless you send it to an archiologist...

Be carefull when guessing what the chip is, I have seen many which are not what they have been claimed or believed to be.

I have ECU's if you need one and of course chips.

[driftin8ez]

what are you looking to get for a stock ecu? I didn't take anyone's warnings and now you guessed it. Ecu is ****ed.

[BEST1TUNING.COM]

yeah the glue sux. $150 for a stock one

[driftin8ez]

I saw that but i wont have that for weeks. It's from japan and doesn't end till friday. I'll keep an eye out as a last resort.

[biosehnsucht]

You don't want a mystery ECU anyways. You can't know for sure what injectors and MAF it's for, and what other changes there might be.

Even buying a generic "stage 1" upgrade can be dangerous of it doesn't explicitly state what it's meant for, and even then you need to make sure your hardware matches that.

[driftin8ez]

Never mind just picked up a top fuel tuned and socketed ecu off egay. It shows pics of the eprom and there is no glue just a topfuel chip and a socket. Cant wait to get it. Now i will have a top fuel tune for stock maf or a mine's tune for my j30 maf. Hmmm which to use???

[Nunook]

I cleaned that stuff off of my friends Mines sr20 ecu.If u have a dremel and time it can be done.
