Does anyone have any....even the slightest idea, where i can find more information on this piggyback unit?

Or even know how to tune with it?

Its called Blitz Multi Fuel Computer System. I hear its a REAL old unit.



I've done MANY MANY searches here, on google, other forums including rx7club.com, bcrx7.com, but just cant find a good answer..... is it just too old? This piggyback unit came with the car when i bought it from my friend.... and he never had the chance to hook it up or mess with it.



Since im running higher boost than stock, this would at least aid me in preventing detonation/fuel cut, etc.



Heres some pics.... hopefully someone has an answer https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

Thanks guys..

looks similar to an fcon!



spin some knobs and add more fuel lol

Well, I would need a wideband to safely tune this thing..correct?



I have a narrowband flashy gauge that doesnt work half the time, and it only displays lean stoich and rich, so not much help with that....



Im have little to no knowlege in tuning..... what do those knobs even do? lol



thanks.

Yes that is a old unit around the same time as the vpc's and gcc's. worked pretty good for its day... wide bands were not really used back when it was out but you will need an A/F meter..basically turn knobs to adjust fuel..

i would just ebay it.....those you turn the knob and pray lol
