well a lot of people on ebay are selling chips that go into the ecu, their around 40 and lower and have some names like skunk2, and mugen and im just wondering if anyone has one of these or has ever installed one. it looks hella tough. i dont know much about sodering (sp) so i wouldn’t touch it, but must you sauder it in there or does it just click? TIA.
well, dan(the g2guru dan) talked about chipping your own ecu’s awhile back. And he said that it does take some soldering (yes, thats the correct spelling). He also mentioned that it wasn’t a really easy solder job.
if you plan on doing it yourself you’ll need a soldering gun/iron and i’d recommend buying something to practice with first.
Hey redstar, ever seen any chips for non-vtec ecu’s?
Also, I’m wondering how you’re supposed to know if you’re getting a good chip and it actually does what the seller says it does. I mean are you just supposed to take their word for it?
Dammit I have been looking for a picture of a chipped LS ecu for the longest. I can solder it in, I have lots of experience, I only need to know if the PR4 ECU needs any resistors or a cmos latching chip. Someones gotta have a pic!
i’ll let you know this much…I have watched them chip computers before and if you don’t know what your doing i would not suggest trying it at all…This is something that requires knowledge of computer chips and circuit boards…
leeo
how much does it cost to get a chip installed?
here’s your pic per request 
woah… okay i feel dumb looking at that picture.
, i took out my ECU this weekend to check out my part# on it…
this is what i found…
in my 93 RS integra…
37820-PR4-A11
which matches PhatSI’s(forsale add) Part# for the 90-91 non vtec ECUs
next, in the pic you’ll see the 3 parts you gotta solder in…
only thing is this…
where you put the socket in for the actual chip… in my ecu, there wasnt a chip there to begin with, it does have all the pads for a chip to be soldered in, it just didnt have one…
in this pic, you’re looking at a Vtec ecu so you are seeing another circuit board(back side facing up) that the non vtec doesnt have.
i really need to talk to g2guru about this.
but this is what i think… that the non vtec ecu just needs all those parts soldered in and it’ll work fine.
RedStarGsr: I have seen those too and seem attractive for the price but soldering is kind of difficult if you don’t have any experience in electronics (like me) so you should better get it done by somebody who has any experience with that type of job.
93integraRS: Where did you get your ECU chipped? I had mine done by superchips. It’s probably the same job. They soldered a socket and put in a programable rom chip. I can upload new programs for it in my superchips retailer. http://www.superchips.com/acura.htm
The link gives a brief description of the performance gains.
Hope this helps.
yusuke, mine’s not chipped yet… i think g2guru posted that pic on bseries.net … would you be willing to send me the program u got from superchip so i can analize it? i’m at college and we have ways to look at the data. email me at rwkruger28@hotmail.com if you are willing.
or did i missunderstand you, and you have to take the chip in and have the superchip retailer upload the program?
I wish I had the programs for my ecu but sadly i have to take the ecu to the speed shop so that they can reprogram it. I had a friend that worked there and he told me that the guy who worked on my ecu could download the programs from somewhere in the superchips webpage or ftp or something. He would then take the removable rom chip from my ecu and put it in a socket that has some type of interface with a PC and then he could upload them to the chip. Superchips has a lot of programs for 92-93 tegs but I have only tried out two. The first one was kind of mild but the one I have right now made an noticeable improvement. I remember I once found a page where you could download programs for ecu’s but I don’t know where I have that bookmark. I have to check back home (i’m at work right now), I’ll let you know later if I still have it.
cool thanks

Yes, most ECUs don’t have the EPROM and CMOS chips in them - they are added, along with the jump resistor at J1. Only a very few have them already in from the factory (like my P61) in which you have to remove the old EPROM. For those that are blank, the ECU runs off of the program that is on the big 64 pin chip above the empty EMPROM and CMOS socket locations, covered with the lable “28 Pin Low Profile DIP Socket” in Dan’s pic in your above post.
Yes, that pic is of a vtec ecu. ANyone have a pic of a chipped PR4 90-91 (or 92-93) non vtec ecu? SOmeone is probably just going to have to open theirs up and take a pic so that we all can know, this secret has been secret too long. I know the socket has to go in, and there is a space where the cmos chip could go if needed, but there are multiple locations where a resistor could be placed. Also it would be helpful to know the value of the resistor. The resistor is the most important thing to know for sure, and thats why I need a pic. Yusuke, that page with the programs that can be downloaded would be very helpful if you can find it.
I have never chipped a non-VTEC ECU. However, I have done a few VTEC ECUs. Only P28 and P72 though. The CMOS Latching chip is needed as well as the 28 pin dip socket and resistor (same value). On the P28 I also needed a jumper (bus wire) to put at location J1. I will open my P28 up tonight and take a picture. Look for this post tomorrow…there will be another ECU pic.
dammit dan you were my last hope, I was hoping you had done a non vtec ecu. Someone please take a pic for all of us who want to see.
Ok guys, I’ll be taking out my ECU this afternoon and taking a picture of it’s interior. Expect it later this evening.
i’ll take mine out too. my digital camera sux tho 
i tried to take pics when i had it out but it was too dark in my house even with the lights on and the camera wouldnt focus well enuf
hopefully during the day outside it’ll work better
