I'm trying to data log on my 85 vette ( 870 ecu). Could anyone tell me if the Winaldl program compatible with vista? Or do I need an older program i.e window XP or 2000 for this to work properly ? I downloaded the program from the werbsite (http://winaldl.joby.se/winaldl_109f.exe) and was able to data log from my ECU, but when I click "save file" it creates a file but the files are not save on my hard drive. I've done a complete search on my hard drive and found nothing. Can some one help me out?

Hi
I have an 85 and have used Winaldl..
I have managed to download the program in Vista but have not used it . I get an info that the com 1 port is not available.
I have on an older laptop windows 2000 professional and that works great. I had an Autoxray before and that was not usable with the 85 ECM.
If I remember correctly I think the values are stored in the program files some place. I had to search quite a lot as I do not think it was said where they were stored.
The Winaldl seem to work great.
What I miss in the program or in the ECM is to be able to read the BLM s stored in the ECM so that I can see how the engine is after having driven it under load. Do you by any chance know how to do that. Because driving an 85 with the Winaldl connected isnot very wise as there can be to much knocks because the spark knock advance andretract is disabled.
Good luck

 

When I get the message teliing me the com port is unavailable I would go into my computer and change the com port and then go back into winaldl and select the comport to correspond to the setting on my computer. I just learning to deal with the program ..... I have not learned much on how to read the info... I do know if the BLM is reading in between 124 to 132 it's pretty good. Anything in the BLM file that's below 128 is running rich. Anything above 128 is running lean. I hope this answers your question.

 

Hi .Thanks for the input. Yes you are right about the BLM and INT. What I wanted is to read the BLM that is stored in the memory after having driven the car without having the winaldl connected, but that seem to be difficult.
You are right regarding the INT and BLM. The INT is allright between 128 +/- 6 or as some also say 128 +/- 10. If the integrator is within +/- 6 of 128 the BLM is within the control area If the BLM is low the ECM lean the fuel so that the integrator is right and the opposite if the BLM is high. If the INtegrator cannot be within the good area then the car will go either rich or lean all after the integrators values. If the BLM is low one can regulate the fuel pressure or reprogram the Chip. But care must be taken leaning the fuel by fuelpressure because when the throttle is about 80% the O2 sensor is disabled and the engine goes open loop and the fuel delivery is dependent of the TPS and the duty cycle (this is programmed in the chip for a specific fuel pressure)the TPS sets in the ECM. By decreasing the fuel pressure there is a chance that the engine will be too lean and that is not good because of heating. Well I put in GenIII fuelinjectors in my 85 bought at FIC. Jon gives an excellent service and the injectors are matched. My INT is very good and the BLM is 110 at idle which mean I have too high fuel pressure at idle. This is due to a hotter cam with less vacuum to decrease the fuelpressure enough. The car went fantastic and the response was great. Shall dyno it later this year (this for info)
