it's almost a alfa romeo spider
i have 22 pound injectors on the car now..is it air flow, the ecu?
No, not with a stock configuration... I do have 12 mm cams (and a modified head), but the stock L-Jet cannot handle these mods under load. Under 3k RPMs and / or if increasing speed gently and steadily the L-Jet keeps up, but under the smallest load above 3k RPMS, whether going slightly uphill or depressing the accelerator to increase speed, the car will run lean, ping, etc. (I have also seen this situation in a friend's 1984 Spider that was running with 11 mm cams.) The L-Jet is not a programmable unit and the stock set-up has always had that limitation.... I think there's even a couple folks who have closer to 12mm and hot heads too that are doing just fine on stock ECU and ignition components. (Zunige being one IIRC) ...
Yes, I am talking about putting high lift cams (11 mm or higher) with an all stock set-up - and all OEM components working as they should.zunige.. what size injectors are they useing? stock? those are only 16 lbs injectors, that would make it ping, sputter..
