That did it. I should have checked that, feel rather stupid now. But windows usually comes up with an error message about the drivers, this mac had no such message, and in the hardware utility it showed it as a serial converter, so i assumed the drivers were already there.

Thanks.

Not sure if this is a TS issue or aan issue with my ignorance of the mac os but :

I have installed the most recent vertion of TS on my new macbook pro, and TS runs fine. But I cant seem to get my microsquirt module to communicate.

I am using a USB/serial converter (its the unit that DIY autotune ...

THANK YOU!!

I kept typing in "map mixer" and "map sequencer" .....

Hi.

Been searching for awhile no and can't seem to find the old thread on this.

Bruce or Al i think built a circuit to compbine individual MAP sensor signals ( mainly for ITB use ) to allow for a better indication of engine load.
The circuit was condenced quite a bit by other users...

Is this ...

[quote]As for timing I get it now I think. The megamanual is just a really long read then I started reading about timing offsets and was looking at other people's maps and it shows like 6* of advance and they say "note there's a 12* offset" so it's really 18*? I'm not sure if I'm understanding that ...

[quote]also, the disk that came with the setup has a megatune program on it but i cant get it to work, my computer has vista on it, will this matter[/quote]

Do you mean that the program wont work? or simply that you cant get it to communicate with the MS?

If your computer has Vista it is ...

kinda have to agree, its doubtfull that you hurt anything, sieriously anyway, though it is easy to burn up a coil or coil driver if the settings are not correct. Dont panic, you ( like most ) will be able to get it running in short order if you take some time to do a bit of homework. Follow the link ...

You NEED to start here, http://www.megamanual.com/mtabcon.htm do some reading, I know there is a lot to digest, But it will answer 99.99% of your questions. Start with the Megatune section and try to get comms, If you cant communicate with MS then there is no way you will be able to set it up and ...

Check out the threads dealing with MSII and low impeadance injectors, or Goto Diy auto tune and check out the Megemeat 2008.
Basicly the V3 board and MSII has problems with the flyback circuit on [b][i]some[/i][/b] aplications using low impeanance injectors, there are a cfew recomended repairs, the ...

Are you running high or low impreadance injectors?

I belive that is just a visual referance to illistrate low to high values. It is usefull if you have a number ( bin ) way higher or lower than adjoining bins.

I was lucky enough to find a GM TB that had SAE fittings already in it, they are pipe thread into tje TB, wish I could tell you what they came off. I [b][i]think[/i][/b] they came from an old S10. I just swapped the pod out the the 454 TB I am using. Joe

I have had great service from both DIY-Autotune and Glens Garage.

[quote]Also I'd be leary about doing business with anny company stating that Corky Bell's "Maximum Boost" is THE tuning bible[/quote]

Read that book years ago, have to look into it again now that i am more learned ( thanks to MS ...

could you post a data-log, also it would be helpfull to know the code version etc.

is the MS controlling the IAC motor?

What is your timing doing? I noticed on My El-comino that leaving the timing curve flat at and near idle made it much more steady.

Did i see your log right? to me it looks like your map drops way down your injectors shut off, could you acually post the log file and is there a way to add a comment as to exactly when it shut down?

Joe, this is Joe :lol: , I actually agree with you about the grounding through the throttle cable, and i also agree that [b][i]just[/i][/b] a railed TPS will not cause a stut down, however a bad signal return can, its happened to me. mine was because i tied the HEI module ground to the return ground ...

Ok, here is another scenario, let us assume that because your datalog showed 20mpa, that the TV was closed. A bad ground on your sensor return would cause the TPS to read full open, it also would most likely cause MS to shut down. When i first installed my Dads unit with the relay box i forgot to ...

I have to go with the bad ground here, unless somehow you have physicly mounted the tps wrong, witch does not explain the low MAP value, a binding or grounding throug the throtle cable makes the most sence, givven the fact that everything shut off. i would double chech the chasis ground to the ...
