Re: Datalogging and/or tuning your OBD1 Beretta

Can someone chime in on what the difference of Bin Definition and Datastream Definition is please. Also is the location of the ECM behind the glovebox of a 1990 GTZ? And once located it should be stamped with a 1228707 or 1228708? Mask ID: $8B ECM: 1228707 1228708 Bin definition: 8B.xdf Datastream D...

Will this Strut Tower brace fit?

Im looking for a front strut tower brace. I contacted MRZ but have not received a response....and their website looks like they just sell used cars now. Will this fit a 1990 Beretta GTZ? https://www.ebay.com/itm/Aluminum-Oval-Front-Strut-Tower-Upper-Bar-Brace-for-Chevy-Cavalier-Sunbird-88-94/4010950...

Re: Any easy, cheaper ways to increase MPG?

Weight reduction will help a lot plus will help with acceleration.

I’m in the process of this. Lightweight hood is next.

I hope US body still sells them.

Lexan windows soon on the list with gutted doors.

Re: Running E-85?

I will update but the first hurdle right now is tuning via OBD1.

OBDII with Hptuners is so easy to learn but this whole chip thing with OBD1 is different. So that first then comes the E85.

Running E85 back when I had my Cobalt SS made a big difference....so I plan to play around with this soon.

Re: Running E-85?

Anybody have experience swapping in a Walbro 255 fuel pump and what bigger injectors are used for the Quad 4? I agree a retune would be needed.

Running E-85?

Anyone have any experience running E-85 on a Quad 4? Will the stock Quad 4 injectors and fuel pump provide enough support?

I understand a tune is crucial thus tuning research in progress.

Re: Radiator for a 1990 GTZ?

Yes I have tried but with no luck. Autozone claimed they had one but it was a total universal that was too long.

I wonder if the automatic Beretta will work with a hose change.
