6 bolt swap with DSM link

[redeclipse7782]

As far as re-wiring goes, what has to be re-wired when putting a 6 bolt engine in a 97 GSX and using dsmlink? I changed the spark plugs on the coil pack to 3214. Do I want to check CAM inversion>? Should i switch them back to 4123? Is there anything else that needs to be re-wired?

To sum up what is everything that needs to be re-wired when doing a 6 bolt swap and using dsmlink.

Thanks,
-Brian

you dont need to swap the spark plugs if you have a 97gsx thats saying you still have the stock ecu. you need a 1g cas one of a 94 model is prefered but you can use any 1g cas.
on your cranshaft sensor plug wire the blue wire to the yellow of the 1g cas, and the red and black are you power and ground so wire the black and red from you crankshaft positoin sensor to the red and black on the 1g cas. the white wire on the 1g cas goes to the blu wire from the 2g cas sensor plug. and just put something over ther red and black wire on the 2g cas plug cause they are not used. other than that everything plugs in wher it should. about the dsm link you will need a 95 ecu

Assuming you have a full 6 bolt swap (1g CAS and head) and a '95 EPROM ECU:

The spark plug wires will need to be swapped.
The CAS inversion will need to be checked (the only way it'd be left unchecked is if you put it in a '95-'96).

I would assume he's running a 97 ECU. would the inversion still apply then? and also isn' that when mitsu changed back to the coils being wired/fired the same as a 1st gen?

It's been a while since i've mesed w/ anything requiring socketing an EPROM. But the last link i tuned ( i didn't install it though) it had the CAS inversion checked and it was a 99 GSX running a full 6 bolt block and head. A local shop is buying me the setup to flash chips for hondas with a system called "CROME", so he can "get rich quick" haha. I'll make some good money off it but, God i hate tuning that way, but there seems to be a better profit marin in that compared to SDSEFI and the ACCEL Gen VII. The sds is not cheap fr as little capabilities as ou have, but the etup is sper simle an tuning is a PITA, and Accell's just cost a shit ton of money.

You can't use a 97 ecu for DSMlink, it must be a 95 eprom ecu.

Straight from http://dsmlink.com/faq.html:

For the 2G guys, the '95-'96 style Cam Angle Sensor (CAS) sends out a signal that's electrically "inverted" from other DSM cam sensors (1G or '97+ style). When you put a '95 ECU into a car with a non-95 CAS, the ECU ends up swapping the firing order of the injectors. In most cases, this produces very little noticeable difference in drive quality. But we offer the option to invert the CAS signal anyway just in case. You can selectively invert this signal with the DSMLink software as you wish. You will still need to swap your spark wires, though. We can't control spark firing order in the EPROM at crank time. So even with CAS inversion, you still have to swap plug wire 1 with 2 and 3 with 4.

So yes, he still has to use the cas inversion because he is not using a 95-96 CAS.

I'm really interested in this thread. I've got my car in the shop and they are installing a 6 bolt with a 2g head. From everything that I've read, it works perfect for a drop in and I won't need to rework any wiring. So if I plan on going with DSM Link (which will be in 2 years), will I need to swap the spark plug wires and then invert my signal with DSM Link?

That is correct, the spark plug wires will need to be swapped and the cas signal will need to be inverted through DSMlink, assuming you have a 97-99 cas. However, in 2 years version 3 of DSMlink should be out and then things may change again. Cross your fingers

Are you assuming he just doesn't have DSMlink yet? Because if so, then he can't run DSMlink and will have no way to check the CAS inversion.

The way I read this (as it is a bit confusing to me...maybe because I've read it like 30 times tonight) is that if you put your '95 EPROM ECU in a car with a '95 or '96 CAS (usually the ones not at the end of the intake cam), then you don't have to check it. This is because the '95 ECU is looking for an "inverted" signal coming from the CAS. And that ECU is usually associated with the '95 and '96 CAS. But if you put the '95 ECU with a 1g CAS or with a '97+ CAS, then the signal coming from the CAS isn't inverted, so DSMlink has to invert it for the ECU to properly read it.

Here is the info directly from the DSMlink site (please correct me if I'm reading it wrong):

- What does CAS inversion mean?

For 1G DSMLink, nothing. For the 2G guys, the '95-'96 style Cam Angle Sensor (CAS) sends out a signal that's electrically "inverted" from other DSM cam sensors (1G or '97+ style). When you put a '95 ECU into a car with a non-95 CAS, the ECU ends up swapping the firing order of the injectors. In most cases, this produces very little noticeable difference in drive quality.

According to the Magnus 1gina2g document:

On a 97+ car with a stock 2g head, no plug swap is required. If you're running a 1g head, I believe it is though.

Very good info for me, thanks! I've re-tuned 2 of them a local guy did he and tuned them really badly, almost as if to blow your motor on purpose. I've never got to install or set up the the main options DSMlink, I've just remapped them. I've had more experience with the regular LINK Click Here

Always looking for tidbits of info like that to keep as up to date as i can on as many systems as i can (thus making me more valuable). I'm doing a Full setup on a regular Stand Alone ECu for eh WiKi here soon. I'd like to get more on DSMlink for my own knowledge. I'm gonna see if I have the manual for DSMlink in .pds, if not i'll have to find a copy

There is a few bits of good info in the faq's: DSMLink - FAQ

Good links guys, thanks! But the more i read up on these piggyback units the more i'm thankfull that i've dedicated 10+ years to stand alone systems like teh accell gen 5, autronic and haltech... i can run my lawnmower with it, my car, a V12 jag IT's like the stereo, you total the car, ou take it out , order a new harness and put it on the next one

One of the crappiest systems i've seen is this tuborxs Utec for subarus it's like a bad DOS verson of pong where you're just trying to get you name typed in for the high score You actually have to FTP connect to the ECU, get the info, log a run , change the info and then reflash the eprom EVERY TIME..MY GOD!!!!!! At least DSM link has decent software.

Not dogging th DSMlink at all, it's been great from my experiences, but i love the unlimited capabilityies of full configurable outputs, inputs and PWM out..sory, way off topic i guess
