Re: 1227749 ECM into other vehicle. No-sir, no oil level sensor on the SyTys MV

Re: Fuel Shut off... Hi Dig, Hi Sam. I know I might be a wet diaper for bringing this up, but if you have a 7730 (do you?) car, a switch to the TurboGranPrix code and a map sensor swap is all you need. From there, it is a few tweaks to the fuel & spark tables. I did it to a 3.1 in a 90...

Do you know where I might find more info on the 3.8 cars with two GN turbos? I'm really curious if they spooled well with a stock torque convertor. They appear to be so close to the 17c in terms of flow, it may be useful. I have a couple GN units as well. BTW, the wheels on both sides of...

A good quality cap and ignition wire set will cure the shudder 8 of 10 times. It take more zap to jump the plug gap as combustion pressures rize. Old wires often have too much resistance or cracked insulation that cause problems under boost. Not sure of your climate, but is the problem...

Thanks jwaller. Any Idea how the stock TDO6 compares to the 86-87 GN turbo? Hard to believ, I'm looking to use the *smaller* of the two. <g> That's sick. MIke v

Hiyall I have two stock turbos that I'd like to run on a 4.3 buildup. I fugure they are good for 550cfm each with reasonable efficincy at lesser numbers. I'm worried about getting enough flow to spool them before 3,000 RPM. I am building custom headers. I have larger port AL heads, which...

I still haven't really clearly seen where to set the wastegate control in the bin. any clues to offer? Hi Tim, 0x03C2 F70_TABLE Desired Boost Pressure Base vs NTRPMX and NTPSLD kPa | 37.5% 50.0% 62.5% 75.0% 87.5% 100% ---------------------------------------------...

The homebuilt stand sounds cool. It sounds like you'll be running pretty rich with 28's and the stock bin. But you seem to have planned for that. Diddling the fuel pressure helps, but has its limitations. As for spark tables, I think the Syclone (torky low rpm six) might be a closer...

Tim, you mentioned using a 7749. Does your engine have a distributor? I thought the 3.1 had coilpaks, in which case, I would have leaned toward a 7730 with the turbo granprix code. Anyway, just curious. Thx, Mike V

Hi Tim, Can you put your stock injectors back in until you're done with the break-in of the cam? Using cylinder volume-to- injrctor size ratio, you'd be close on the tune with the stock bin and 21lbs injectors on a 3.1L. Just a thought. Mike V
