Hey whats going on everyone? i Just recently was/are doing a 5 spd swap in my 97 lude originally tripotronic w/the h22a4. Anyways, i ended up putting in a f22 vtec tranny from an accord and slapped in a exedy clutch and fidenza 8 pound flywheel. Now, what i am wondering is everything went smooth up until i put the 1997 5spd ecu in. When i use my original ecu it runs and drive but obviously the check engine lights on in it. But when i try the 5spd ecu it just turns over. Can it possibly be the safety neutral switch? i didnt hook it up at all. so theres that idea. anyone else have any other ideas? OR have can tell me what pins to switch out or somehow bypass if it is the problem? and how to bypass?
i believe this link tells you something about it, maybe i am just tired but its a very technical tread....and a little hard to understand.
i have altered pins on the ecu in my old ek. but to me, pin3 is so blunt i just dont understand what he means (in the link). when searching for a ecu pin out for the 97 prelude, i see nothing about a safety neutral switch. i am soo f'd, a little help please?
It only turns over? I bet you wired up the switch from the clutch pedal from the starter relay to the ground huh? i would NOT suggest doing this. Its not starting up because you have to program the ECU to work with your existing keys (You'll need the red key and a trip to honda plus ~$100+). Its cranking because you grounded the starter relay, which means it will ALWAYS crank even if the key isnt programmed to the car... See my writeup.... You should modify the ECU or else you'll have to go to honda to reprogram the whole key thing to work and such (more $$$!!)
Read my writeup and ask away

as for rewiring anything, i havent touched anything yet, all the wires are at factory auto spots (probably a plus for right now until i figure out what i am really suppose to be doing)
now for the key thing, i doesnt look like there is any chip mechanism in my key, it is a 1997, and i am using the stock ignition. the only things i really changed where tranny related. BUT i do know with the rsx's you need the right key for the ecu.
it does run fine when the auto ecu is in, just the CEL is on. and i cant register it in CT when the CEL is on. But when 5 spd ecu it just turns over, it doesnt start. any other ideas or input? is there a couple wires i need to switch? Please let me know you guyss, thanks so much for the input so far!

I explained it in my post above. It sounds like everything is wired up properly because it starts with the auto ecu... Its because you grounded the starter relay so even if you dont have the properly programmed key, it'll always crank. Its the same thing with the RSX.... Modify your automatic ECU and the cell will be gone.
OHH nice, I think i am following ya. so you take RP13 and put it where RP14 is, correct? Do you just de solder RP14 and take it out completely as well?
yeep, remove from RP13 and put onto RP14 and your done. The pictures he posted are a bit confusing, but the RP14 slot should be empty on a stock ecu (in the picture is occupied already) Be very careful if you DIY and arent confident!
yeah, i am a little worried of doing it, i am going to see if my buddy wouldnt mind doing it first, but i must admit, i dont want to f' it up. so alot of people doing the swap say you just need the 5 spd ecu, they never mention the key though. wish they would have, glad to see that there are people like you on this forum that professional lol. so on a one to ten how hard of a task would you say resoldering this resistor is?
Moving the resistor isnt hard, its just nerve racking. If you did your swap, you can do this. Its just tedious. If your worried, take it to a reputable mom and pop electronics repair shop and have them do it for a few bucks.
I'll give it at 4

4, meh. It might be worth paying someone else to do it. I'm going to try this first and then I'll let you know how it goes in a couple days - probably on Thursday. Thanks again for your help. I really appreciate it. Take care and wish me luck!
nice, i am torn between doing it myself and having someone doing it for me...did you using the desolder-er that "sucks" up the old solder? what did you just do, put the tip of the iron to the old solder and melt it?i am kind of just afraid of burning something important in my board...you know?

I just heated up the solder around the resistor and pulled it off with tweezers. I then soldered it back in place. I have de-soldering wick, but I didn't need it.
No bulb sucker here. Just push off the resistor gently while alternating melting the ends. Then put it on RP14 and melt some solder on there. It was very crooked when I put it back on but it was enough to make contact and get rid of the crappy idle and CEL

Anyone who did this..
Did you guys melt the leads and the solder underneath the circuit board at all or just the ones at the top? Please let me know. Thanks.
