Title: How long does it take you to desolder a virgin ecu?
Post by: 98vtec on September 13, 2009, 02:34:48 AM
one that needs no conversions.  Say a virgin p28. 

How long does it take you and what tool do you use?

5 mins tops

I use a desoldering gun. (soldering iron with vac pump)
wire snips (cut the leads on the stock rom
Heat Gun (heat the remaining leads)
Small needle nose pliers or tweezers (pull out the leads when solder is molten)
Solder wick (used to clean up the holes)
Solder (flux cored)

takes about 10 mins to solder a new socket in, clean it up with propanol, and spray PCB sealant.

it shouldnt take long with the right tools.
Just cut the leads off the old chip, its easier that way and you dont risk pulliing the copper wires out of the board if you pull it out to hard.

I never investsed in anything but braid so it takes time but I rarely do ecu's maybe a couple every so often for a couple shops I work with.


I would say with braid 15-20 minutes to desolder waiting for the iron to heat back up and cutting the braid as you go along


Obdo stuff is fun. I just cut out the stock chip so you dont have to worry about prying up on the stock eprom and pulling traces. This applies to p13's and the odd every so often eprom already installed usdm oem obd1 honda ecu's.



After how much I have spent on braid over the years I could of bought some nice equipment which I think anyone who plans on doing this more than a couple times should. Time is money.

I have only done a couple total, but that is what I use as well. I was ~10min out, 15min in.

About 15 minutes with one of these

Except mine is the radio shack one. Gotta replace the tip quite often or else you start fucking shit up.

I use the same one I sharpen my tips with a dremel. they work better with a smaller tip

well i always hated using the copper braid and the little suckers so i finally gave in and bought a hakko gun with the built in pump.

i like these. once you get a rhythm going its great. 5-10 min to desolder i would say.

I'm getting a desoldering station.  Fuck the dumb manual bulb crap.

im hoping this just takes the agony away from chipping an ecu.  It is a pain in the ass, but if you can find a gold mine for ecu's you can make some good money doing it.  The only thing i refuse to do is send a basemap with it unless im doing the tuning.  Giving the customer a basemap gives them more reason to postpone getting tuning.  I dont know how often i see people with chipped ecu's and they think they have a tuned engine.

Yeah, I don't do basemaps either.

boost basemaps=trouble


Somebody who has a simple all motor build basemap action your not going to get yourself in trouble


I have been saying for years i was going to buy a desoldering station still havent done it and probably never will. I guess I have just got use to using braid.

I need to stop sending basemaps too.

People are fucking idiots. They think a basemap means a tuned ecu, so they go out and beat on their fucking cars. Then when something bad happens, they come back and bitch at the tuner. It's fucking ridiculous. I'm getting really tired of that shit.

If they fabricate a valid reason why they need a basemap, then it's okay to let them have one with a 1.5 psi boost cut.

I still don't do it because I'm not interested in hearing complaints about how the car idles, when the TB set screw is missing or whatever is retarded about the car.

Wow you are all fast take me 30-45. I for some reason clean all the crap off with iso alcohol first takes some time. I use braid and the radio shack bulb thing.

I am not a fan of basemaps either. I don’t do may tunes.

Too long with the manual bulb desoldering iron.  I would love a desoldering station, but I haven't chipped an ECU for several months.

Title: Re: How long does it take you to desolder a virgin ecu?
Post by: chris on September 14, 2009, 01:18:54 AM
I stopped doing ecu's/basemaps about 3 years ago due to a scholar after 6 months on a basemap broke a ringland and had his dad call me to bitch about his car blowing up.


Or you get my shit runs rich


Send me a socketed ecu and let them figure out the rest.

Ive pretty much stopped tuning cars If I get the right type of person I'll tune for them but ive got nothing but a long streak of white trash broke ass retards calling me wanting tuned and bitching about what I charge $250 then asking if they can get a deal or for a basemap for $50.
     Like I want to jump up for nothing and install my gear and drive around some piece of shit with exhuast leaks countless other dumb dumbs that make what should have been about 4hrs into all fucking day.

I take that back I still do ecu's and have been learning k-pro but that is not via internet madness. Just bay area stuff since everyone I live lives off welfare.

x2 i have the rythem down with that takes me about 5min to desolder. i also have the radioshack desolder it works great if there is a part already soldered in but i like the solder sucker with my iron for chipping.
I need to buy 1 of those fancy ching chang chong machines JD gots with a Desoldering station.

word.   Its not worth the annoying phone calls.  I did it once, told the guy not to call me when the car doesnt run smooth because its going to need tuning.  What do you know, one week later he calls me asking why the car runs funky.  ugh.  that was it.

What really fucking irritates me is people who charge money to make a basemap for a customer when its likely just some bullshit they pulled of the xenocron bins or something that came from a previous tune.

Post by: PhilStubbs on September 14, 2009, 05:27:48 PM
i have always charged for basemaps cause i spent the time tuning the original car that i am basing their map from, i spent my own money on all of my tuning equipment and i spent years learning everything to be able to do it. i dont charge a lot, considering what is spent on the chip, packaging and shipping, i end up with enough money for a beer. and luckily i dont get those annoying calls or emails that their car doesnt run right. im sure their car isnt perfect, but i guess i managed to drive the point home that it was only meant for them to drive the car to a tuner.

Post by: 98vtec on September 14, 2009, 06:03:05 PM
yea and you got paid to tune the car.


you dont think everyone else did the same as you?  i've paid for all my stuff as well but i still refuse to make people pay for something that is a guess to which will run the car.  regardless its still a basemap.
Title: Re: How long does it take you to desolder a virgin ecu?
Post by: PhilStubbs on September 14, 2009, 06:18:05 PM
but its also your time and your knowledge at work. i was being literal when i said when all is said and done, i can buy a beer. i would have to do a hundred basemaps a day to make a living with what i charge. are you saying you pay for the chip, postage and packaging? if someone came to me in person with their own chip and asked for a basemap, i would just give it to them cause i didnt have to provide anything except a few min to make a couple quick changes and burn the chip. thats good business, but all of my basemaps are sent halfway across the country.

also, people expect to pay for it. every single time i have been asked for a basemap the question is "how much for a basemap?" not "can i get a free basemap?"

A simple all motor build a basemap will run the car fine for years. Back in the olden days all we had was the mugen program and we cranked up fuel pressure as needed



Funny because really most of the b series stuff is making the same power as they did 7-8 years ago + maybe 10 hp. Its just more documented now due to the interweb. Southern california was trolling with 11/12 sec all motor street cars all on the same damn bin file for god knows how long. Skunk2 ran 10's on that mugen program and a vtec controller when they were B series


The boosted applications is where you will get yourself in trouble selling chips. In reality its not worth the hassle to make 10 bucks.

Post by: chris on September 14, 2009, 06:22:43 PM
I agree your looking at about 6-7 bucks for shipping/chip/static bag/tape/gas and that doesnt include your time

Skunk2 ran 10's on that mugen program and a vtec controller when they were B series

And then Doug MacMillan tuned their car and they ran some more 10's.

Hakko 808 -> 3 min tops. Can be had for ~$120 on sale.


Braid, manual pumps, etc? All bullshit. Why waste your time.



With proper technique, an ECU can be socketed in about 5mins.
