Lc-1 is better than nothing, but the NGK is the way to go! More robust, with a trade off of slower response time compared to the bosch. Its just the design the surface area to clog with lead is much bigger on the ngk, so it takes longer to fail.

I need to bypass the 9s; I know it won;t be easy, but even an 8.99 will be good enough to get banned for a long time.

I am waiting on some parts 8s' does not come cheap and takes time to get it sorted out.

The bottom line is you can tune it the way you want any af you want and timing........ .under any boost condition or cruising...

I ran the pro as well, and it would randomly take the timing to 34 degrees under boost,,,,,,,,,,,but only once in a while. I could not risk the motor so I had to abort everything stock ecu related, I think everything was EMI related.

This is a typical turbo buick owner of today. He goes to the track and runs 14’s and is pissed. Hits the bulletin boards and is told about tuning but ignores the info. He goes out and buys 4” downpipe, 1200hp turbo, triple valve springs, double pumper, 400 amp alternator, 55lb injectors and Reds chip and ready for the 10’s. But to his surprise he only made it to the 13’s. He is told on the board that his setup can handle 30lbs of boost with alky so that’s his next buy. After not listening on how to tune for alky he blows up the motor and blames all the part manufacturers. Now he looks deeper in this tune thing and sees XFI is better then the rhythm method of birth control. He spends a few thousand on it and gets a startup program and goes to the track. Still pissed he is in the 13’s calls go out to supertuners. Being cheap as most buick guys he won’t pay. He gets a few friends who read some xfi tuning secrets and hit the track. Now he runs 13.0 but flames are shooting out the side of the head and the track is pissed for the oil down. Now the peanut gallery chimes in and says buick sucks and now he drop in a bulletproof LSX  
That is so funny, but true, with the wrong numbers entered it could be all over quick

Norbs - Give us the pros and cons, when and why to switch, total cost, driveability.
The stock ecu does not provide immunity to interference from MSD boxes.
Thanks for getting engaged here Norbs, its all interesting and I'll have to study it all.
Did this (the above) turn out to be the ECM or all that Moates stuff?
Dave, the Moates stuff would corrupt the bin file randomly after powering the ecu down. You could re-flash it and it would be fine for a day, a week,,,,,, then all of a sudden a ecu code pops up bad eeprom. So i had to scrap that plan. Using the chip from Eric it ran great, however at high rpm/boost the mass air signal and during accel would go erratic, and start throwing timing all over the place, knock etc. Then I decided to go SD mode to eliminate the MAF out of the equation, it worked much better, however it still would start doing weird things and I could not get consistant results to hold the timing or the closed loop fuel control steady at WOT. Put the fast in and timing was rock solid, and great fuel control....... .......

Actually you could use the XFI as a safety with alky, and a pressure switch, so that the AF ratio will only be modified when the alky is present,,,,,,,,,,,,top that one top speed

ANd i forgot to mention traction control , so you don;t have to worry about wiping the car out at top end.....becasu e the spinning is controlled, not violent.

Thanks
Can it self learn to the point of making a street friendly good gas mileage daily driver?
I dont see why not, you can put any AF ratio in and timing for cruising speed. Self learn does not come in effect for cranking fuel, accel enrichment, or afterstart, you are on your own for those.

Norbs - Give us the pros and cons, when and why to switch, total cost, driveability.
The stock ecu does not provide immunity to interference from MSD boxes. The timing on the stock ecu is is fixed by gear changes and once you go WOT it is not regulated by boost. I e you can't put in 25 degrees at 5 psi boost, 23 at 1o psi boost, etc. Even with the trans pro you can do it against rpm but not boost. The processor speed is 8mhz compared to 24 mhz. The O2 sensor gain on the WB chips is fixed, xfi its variable, and the correction limits are fixed on the wb chip , xfi its not. XFI has self learning with variable gain, individual timing and fuel control. boost, control, timed boost control, 2 step, 3 step, nitrous control, 4 inputs, 4 aux outputs, 8 analog inputs, datalogging at 20 fps for 24 items. 5 bar map input. Wideband o2 inhibit delay to reduce spikes on wb correction on gear changes. User defined coldstart, after start enrichment, cranking fuel, any injector size , high impedance and low impedance. The cost is about $2000 by the time your done is the con, and the time you need to tune all this in.. Many more features Im just starting out...

Hi , I dont like it can't read the plate........

Tip, check the antifreeze before winter.....  ....carpet looks great
