Thanks that is what I am asking about. (While I appreciate the effort in the writeups on electricity that's not the question I am trying to answer). I like everything about the xfi over the stock ecm except for this issue. It is very frustrating when this happens havin to run two or three...

Bump has anyone experienced this with a holley hp?

Yes that is exactly what is happening. My question is will the holley have the same trouble?

Xfi 2.0 If my battery is low car will crank but check engine light will blink and car won't start. I have to put a battery charger on the car just on 10 amps then car will start when I crank it. This is very annoying. Factory computer would have started under these same conditions. I have a...

Great. Keep using him. And better yet write a letter to your state representative and ask them to eliminate the worthless inspection.

Also you have to perform the inspection every year before you can renew registration. You will also have to get inspection done before you can transfer your registration to Texas from your old state.

all vehicles in Texas have to safety inspection no matter the age, it is $7 or $9 I do not remember the price. It is just another tax on vehicle ownership. The safety inspection is a joke, check lights horn open hood and close hood. Emissions testing go county by county and are done if federal...

No change to computer

last I checked their is still no one making the evaporator for these cars. I would recommend removing it and selling. Not cutting the tubes off.

Fix it now before you spend time tuning the car. https://turbobuick.com/threads/replaced-alternator-now-ve-table-wrong-xfi.461354/

What are our options for holley harness now? Unterminated universal from holley. Cruz performance harness that uses holley coils and his brackets Are their anymore options? I want to run stock Igniton or a later model 4 . waste spark does anyone make replacement harness for those Igniton.

These we all good suggestions thanks. On simular topic. I have used up all my good quality insulated crimp connectors. I don't remember where I bought them. Looking for both insulated ones and the insulated that can heat shrink to seal. Any suggestions on that. I am thinning I should...

Thanks. Where did you get that junction box? I like that it has a heavy terminal not a numer 10 like the one I linked. I have a few similar that I robbed off 90's chevy pickup that also include a fuse, I am considering using one of them.

Thanks for the link. Long term Plan will be to hotwire computer and injectors. Just looking for a short term fix. O2 is pegged negative during cruse can't control. I am going to subtract 10% off the map 100kpa and below, up to 3,000 RPM, leave the rest of it alone. That will get me...

Has anyone come up with a good solution to add an auxilary positive terminal under the hood. I want to get all these added on and "hotwire" circuits off the alternator and get the wiring off the engine. Most of the things I have found on summit or just in general have bad reviews, or they...

I am also considering just subtract 15% from entire ve table that way it will get me back into a range where o2 sensor can control . Or I could turn self tuning back on. But I wasn’t very successful with that originally so I turned it off and tuned myself.

Also as a temporary solution. How successful would I be to take my old map good map and just adjust the injector voltage offset till it is closer to correct. I am looking for a solution that will let me drive this car without redoing the entire be table while I rebuild trans in my pickup

So what are the standard voltage offset numbers for the narrow body Siemens 60 lb injectors.

That was going to be my followup questions, do I need to hotwire the injector harness, and should I be adjusting the voltage offset table. thank you

Okay. I wish I would have known that 3 years ago would have just done it day one. Tuning the car is still fun, like everyone else with these cars I put a lot of work into the part throttle tune and would prefer to doing WOT tuning, not redoing this. Thank you.
