]]> Custom computer chip v5.7 made for your Turbo Buick or Pontiac TTA. This chip has user adjustable features that allow you to do fine tuning of WOT fuel and timing if you wish (need a scantool). Choose either a street chip (pump gas), race chip (race gas), or a chip for alcohol injection. Note the '84/'85 cars with stock ECM do not have the same features. This chip is designed to work with a stock MAF, or Translator/MAF setup.

Street Chip: for use with pump gas (91-94 octane), and will also work with alcohol injection, but not as aggressive as an alcohol chip. Normal max boost is 14-16psi on 91 octane, 16-18psi for 93 octane, WOT fuel will be set up for that boost level, around 18 degrees WOT timing. For the 84/85 hotair cars, typical boost is around 11-14psi. Cars with the 84/85 ECM will NOT have the features of the 86/87 chip.

Alcohol Chip: for use with pump gas when alcohol injection is being used, timing is increased to around 21-23 degrees, boost is increased to the 20-25psi range, along with some other small tweaks to work better with the alcohol. Alcohol injection MUST be used with this chip. The calibration is made for 100% alcohol, no water mixes. Excess knock will occur if the alcohol is turned off and you go to full boost.

Race chip: for use with race fuel only, NO alcohol injection, high timing around 26 degrees depending on octane and combo, more WOT fuel for high boost. I need to know what your goals are, what boost range you're going to run, and octane of the race fuel. I can make the torque converter lock at WOT if you request it. I never set the torque converter to lock at full throttle unless specifically requested.

]]> The Tune Saver is a backup power source for your car's stock computer so it will keep it's memory if the battery dies or is disconnected. Not for the ecu-GN aftermarket ECU. This has nothing to do with the tune programmed onto your chip, as that cannot be erased. This enables the ECM to remember any learned data (BLM), or user parameters, if you have an adjustable chip. Designed for a Turbo Buick with stock computer, but could be used on other cars with tweaks to the wiring. It is plug and play on the Buick, and installs into the single orange wire for the ECM's memory. We normally place it under the MAP sensor, and run the wires down towards the battery. ]]> <![CDATA[TurboTweak Emissions Chip - Buick/TTA]]> https://www.turbotweakstore.com/TurboTweak-Emissions-Chip--BuickTTA_p_75.html Tue, 6 Oct 2026 00:00:00 EST This emissions chip retains all the factory chip emissions programming as well as a couple tweaks here and there to help improve emissions.

]]> This emissions chip retains all the factory chip emissions programming as well as a couple tweaks here and there to help improve emissions. The coolant fan temperature is set higher in this chip to improve emissions, so be mindful of that if doing extended driving, and do not get into boost with it (it may be too lean). As long as your emissions equipment is in place and functioning, you should be able to pass (although I can't guarantee it will pass due to any mods you may have done to the car). If you don't have a cat, or EGR, there is nothing I can do about that. There's nothing special I do in the chip for those situations. When ordering an emissions chip, all I need to know is what year car you have, and the injector type. ]]> <![CDATA[Bailey Engineering Extender (or Extreme) Chip]]> https://www.turbotweakstore.com/Bailey-Engineering-Extender-or-Extreme-Chip_p_77.html Tue, 6 Oct 2026 00:00:00 EST From Bailey EngineeringComputer chip for a Turbo Buick or Pontiac TTA, by Bailey Engineering designed to work with the a Basic Translator, GEN II Translator, or the AXiS Interface if specified (will not work with stock MAF).

From Bailey Engineering
Computer chip for a Turbo Buick or Pontiac TTA, by Bailey Engineering designed to work with the a Basic Translator, GEN II Translator, or the AXiS Interface if specified (will not work with stock MAF). The Extender reads up to 512 gr/sec of air, and the Extreme reads to 768. Takes advantage of the extended airflow range of a newer MAF.
This chip has user adjustable features:

Shift Light: flashes check engine light above desired RPM

DFCO delay: prevents annoying RPM dips while coasting caused by high stall torque converters

Fan Temperature: Select “Street” or “Race” modes

Cruise TCC: Select the vehicle speed for TCC engagement at part throttle

WOT LoGear Spark: Adjust how much extra spark advance is commanded in first and second gear

BLM correction: Adjust for out of spec injectors or fuel pressure, adjusts all BLM’s up or down.

System Options: Control the operation of open and closed loop at cruise and idle.

Enable Launch Assist and Lean Highway Cruise mode.

WOT TCC: Control the MPH at which the Torque Converter Clutch engages at full throttle.

Spoolup Fuel: Adjust how much fuel is delivered during the spoolup phase of full throttle.

LoGear Fuel: Adjust the Air/Fuel ratio for Full throttle operation in first and second gear.

]]> Adjustable chip that must be used with a Powerlogger, and can make corrections to the air/fuel ratio based on wideband readings. You must have a wideband O2 system connected to your Powerlogger to use the closed loop full throttle control. Needs a stock MAF, or a Translator/MAF setup. Not for injectors smaller than 50lb/hr. The chip still uses the stock O2 for all the low end fueling, idle, cruising.

The available user adjustments at this time are:
1 = WOT A/F Ratio - 1st/2nd gear
2 = WOT A/F Ratio - 3rd/4th gear
3 = Mid Boost A/F Ratio - all gears (part throttle)
4 = Base WOT fuel
5 = Spark Timing Offset - 1st/2nd gear
6 = Spark Timing Offset - 3rd/4th gear
7 = WOT TCC Lock MPH
8 = Base Mid Boost fuel (3 to 14psi)

The chip is calibrated specifically for certain widebands, so I need to know if you have a LC-1, PLX, etc. There are some widebands that I don't have calibrations for yet. Basically, the chip works like my 5.7 chip, except there are more adjustable features. It also can read the wideband reading from the Powerlogger and do corrections.

In the chip, you have three target A/F adjustments, mid boost (3-14psi), WOT 1/2 gear, WOT 3/4 gear. If you set an A/F of 11.5, it will try to maintain that as best it can based on info from your wideband. You have to make sure your wideband is working properly so you don't get false info (garbage in, garbage out as they say). The program can add up to 33% fuel, and subtract 10% fuel to maintain the A/F. You can adjust the base WOT fuel to keep the correction inside the "window". I limited the subtraction to 10% so it can't get too crazy pulling fuel if something wrong happens.

Street Chip: for use with pump gas (91-94 octane), and will also work with alcohol injection. 16-17psi boost in most cases (maybe a little lower with 91oct), WOT fuel will be set up for that boost level, around 18 degrees timing. This chip is not available for cars with the 84/85 ECM.

Alcohol Chip: for use with pump gas when alcohol injection is being used, timing is increased to around 21-23 degrees, boost is increased to the 20-25psi range, along with some other small tweaks to work better with the alcohol. Alcohol injection MUST be used with this chip. The calibration is made for 100% alcohol, no water mixes. Excess knock will occur if the alcohol is turned off and you go to full boost.

Race chip: for use with race fuel only, NO alcohol injection, high timing around 26 degrees depending on octane and combo, more WOT fuel for high boost. I need to know what your goals are, what boost range you're going to run, and octane of the race fuel.

All chips are for off-road use only. ]]>
