I'm putting the shopping list together for a fuel injector upgrade. Probably going to go with something in the 75lb/hr range. I currently have a single Walbro 255 Lr/Hr pump in the the Typhoon driving Lucas 42lb/hr injectors and am concerned it isn't enough pump for larger injectors. I've had...

From what I understand the output shaft is syty specific. I'm rebuilding one out of a 92 typhoon at the moment and the rear planet has melted down due to low trans fluid. The output shaft looks like it has been hot and I think it is best to replace it. I've got an output shaft from from a...

Re: wideband choice. I just put a PLX sm-afr in and got the code 59 bits running. It was fairly easy and I'm quite happy with the results. I didn't end up getting a display for the PLX and now wish I had. The only way to see AFR is with data logging and I'd like to have the piece of mind of the...

Re: Passing the Torch - Sportmachines.com How much space are we talking about? I'll donate the space on my server if I have it for the online archive.

Re: PLX DM-5/SM-AFR interfacing with the ecm Did you all just replace the stock O2 sensor with the wideband? All of PLX's docs say to mount it atleast 24" from the turbo. Our stock sensor is about 4" from the turbo. Thoughts? I'm planning on using the stock location but thought I would ask.

Re: Vortec chamber volume? I've got a set sitting in the garage. I can measure them this weekend.

Re: Which PLX Wideband I think I'll opt for something more plug and play for the Typhoon. I might look into that for the Silverado.

I think I've convinced myself to go witht he PLX wideband. Is the PLX sm-afr the way to go or is the M-300 a better choice? Are both supported with code 59? I really like the idea of the DM-100 with multiple devices. I'm planning on starting with the sm-afr with no gauge and adding a DM-100...

Re: Tuning Woes Yeah...I see the same 2.2kpa at idle using DM. I've verified this by looking at the voltage going into the ECM. I've cut the ground on the MAP side and used a jumper to rule out the connector. Same story, low voltage back to ECM when using that ground. I'll take another stab at...

Re: Tuning Woes Talked to Jim Sloan tonight and did some more troubleshooting. What I know: 1. Map and Coolant sensor share same ground to ECM (B6 C307). Unsure of which coolant sensor. I think we have 2. One on intake manifold and one in a head. 2. I get 5 volt reference to map from...

Re: Tuning Woes New map...same problem. A little more troubleshooting and I've narrowed it down to a grounding problem. If Anyone know where the ground wire from the map goes? Does it tie into one of the grounds on the back of the heads? I'm digging through the service manual now and will...

Re: Tuning Woes Did some further testing tonight and I'm 99% sure its the map sensor. I checked the voltage at the map sensor using jumpers. I've got +5 on the reference and .4 on the signal wire at idle. I picked up a 2bar at the local parts store since that is all they stock. I get +5 on the...

Re: Tuning Woes Its not the boost reading I'm looking at. At idle that would be zero. Its the MAP Pressure (Calculated 3-bar from 1 bar).

Re: Tuning Woes I'm not having any problems getting TunerPro to link up with the Ostrich or ALDL. Just the MAP reading issue.

Re: Tuning Woes I think it has the ALDL patch. Jim Sloan did the original tuning on it. Is there a way I can tell by looking at the bin?

Got the Typhoon out of mothballs since the weather is getting nice. Apparently it didn't fix itself over the winter. Darn the luck. I'm still struggling with TunerPro. I'm running version 4.14 with the following xdf and ads files: 1227749_2&3Bar_58_rev6a.ads 58_2&3Bar_Beta_0.9.1.xdf The...

Re: Map values in TunerPro RT/Datamaster I have a 3bar map sensor....Got another ECM in the mail today from Jim Sloan. I'll see if that changes the results. Brian

I'm seeing MAP values of 2.2 in the readout for "Mass Air Pressure (Calculated 3-bar from 1-bar variable)" display field at idle. I'm using the 1227749_2&3bar_58_rev6a.ads ALDL definition file. Where does the value for vacuum (In Hg) come from. It seems to have the right value at idle. I've...

Re: Trans Leaking Ah..that explains it. I'm going to see if I can find a shop in the KC or STL area that can overhaul the 9/11 TC and I'll put it back in. I really appreciate all your help and I was glad you made it to the Nats so we could meet face to face. I'm sorry we didn't have more time...
