ECUflash DATALOGGER or EVOSCAN

[JoEgsX90]

Ok i do not have enough money for DSMLINK, i know it kicks ass!! =) But for now whats better for me to invest 100 and change on EVOSCAN or just a DATALOGGER? MY setup is on my pro.

I believe that your ecu will have a hard time giving you a worthwhile sampling rate with evoscan. Initially 95/96 ecus had a hard time even getting connected. At the moment I think a datalogger is the right answer for you.

One option to consider though is reading up on the evo8 ecu swap, at that point evoscan would be the best way to go and you would have significantly more tuning ability than the SAFC that you are using will allow.

for a 2g if you don't want dsmlink then you should get an safc and eveoscan. The sampling rate for the 95-97 ecu is the same as pocketlogger because it uses the same protocol.

Its up to you if you want to buy an evo ecu or an safc though, they are about the same price used and you won't have a hard time selling either if you decide to go another route. The evo ecu install is probably harder than installing a safc but you'll have a harder time initially learning to tune with evoscan/evo ecu

I have yet to do mine (the car is garaged and the garage is buried by snow) but from what I've read the evo install is as easy or easier than the SAFC but the SAFC is better supported with fewer potential surprised.

I bought evoscan and I give it a big thumbs down. Rates are just not fast enough.

What kind of sampling rates are you getting?

With Pocketlogger I average about 18(+/-2) per second on my '99.

 

[m_0ney_pit]

I was getting 17-18 sample/s with a 99'gsx ecu and 7-9 samples/s with a 97' ecu on pocketlogger.

7-9 samples/s is more than enough resolution to tune with an safc and it worked great for me. The safc rpm resolution just isn't good enough to warrent anthing better.

The reasons to go with evoscan:
Logs knock and has inputs for wideband, looking at thoughs two variables will let you tune your car as good as an safc can.

I dont remember exactly. I was logging on a 95 Eprom ECU so it would be slower than the 98 and 99 ECU's (from what ive read...sorry I didnt think about my 95 ecu before posting). I have a palm that I use now for logging.

Get an safc/2. They are cheap nowadays and relatively easy to tune with.

I believe that evoscan doesn't log knock on 95-96 ecus because it is using obd2 protocol, I'm not sure if it logs knock for 97s but I believe it does just not at the same sampling rate as 98/99 ecus.

Something to consider would be moving to a 98/99 ecu since they are cheap and would let you log knock and have a higher sampling rate.

The long and the short is that 96/97 cars get shafted in the ECU department, no eprom and no MUT.

 

[m_0ney_pit]

Oh my bad I think your right about the 95/96 ecu, I never used it in OBDII mode only MUT.

The 1997 ecu (1997 model year), works flawlessly with evoscan and sample jsut as fast as the 1998. I know this from personal experience with using the evoscan software and the official evoscan cable on my brother august 1996 (early 1997 model year) talon tsi.

So as mentioned, just get a 1997-1999 ecu and get evoscan. The logging perameters are worth the very small investment of swapping in another ecu. You will need to swap firing order. Just as if you were putting in dsmlink in a 1997-1999 car. A little searching will give you all you need to do this. A little advantage to the 1998-1999 ecus is that there are several working on the reflashing characteristic of these ecus. You will need to swap in the reflash plug. But as of now, there are those that apparently can edit the timing and fuel tables. They are still workign on global and dead time fuel control, etc.

Logging an actual knock count instead of having to guess on timing dips is VERY much better to tune your setup. It's worlds better and worlds worth it. Using % injector duty cycle is so much easier to know when you've reached the limit of your injectors. You can't get either option with other 2g logging solutions except for dsmlink.
