 Post subject: pr4 tune anyone?
PostPosted: Mon Jul 14, 2003 5:15 am 
Hi everyone! My current setup is crx with obd0 b18a, greddy sohc kit, fmu:(. I have been reading up on my options for fuel management and it either looks like obd1 conversion with $hondata$, keep my ecu and get $$Zdyne$$, or buy a 100$ chip burner and chip my ecu with Gdyne. I have allmost made up my mind and bought a eprom burner but gdyne comes with the boost tune for the d16 but im pretty sure this will not run properly on a b18 because I looked at the base maps for both engines and they were considerably different. I am ignorant and/or don't have the confidence to modify the tables and was wondering if there is a pr4 boost tune anywhere that has the scaled map because I have some 450s waiting to be installed. I can't be the only person with a ls turbo crx wanting to run Gdyne. Any help would be great, thanks.

Well, first off, if you're using an FMU, you're probably running on stock injectors. This would lead to a leaning condition if you were to use the D16 MAP. This is, obviously, because you wouldn't be flowing as much fuel.

What I would suggest for your current setup would be the GhettoDyne N/A ROM with PR4 fuel and ignition maps. I believe (correct me if I'm wrong) that the injectors are the same size, just pulsed longer (by the looks of the maps).

I have 450cc injectors waiting to be installed, along with scraping the fmu and check valves. What I need is a b18a tune for my pr4 ecu with fuel maps for boost, ignition retard per psi, and the scaled map for the larger 450cc injectors. I don't know if i wasn't clear in my first post, but this is what im looking for and im sure someone can help me out. Thanks in advance. -nevin
