Unichip Map A or B?

[Garrdogg]

Just got my unichip in and installed it yesterday. I was wondering which map to use. I didn't get a check engine light on Map B but can't really tell the difference in the maps as far as power differences. I know they say that you get more power with B but more problems can arise as well. Any information would be helpful. 2001 Tundra 4.7L, ss autochrome race headers, flowmaster series 50 dual exhaust, volant coldair intake, helix throttle body, and unichip.

Most of us run Map B. I know I can feel a difference, despite all the changes I went through (...details are here - scroll up to see my follow-on post for more info).

If you just received your Unichip and were not part of the Group Buy, I would assume you have the newer PnP harness so my original issues are probably not related, but I figured I'd mention it.

BTW, updated instructions (which go over Map A vs. Map B in more detail and which by now should be in circulation so you probably already have them?) are here. Refer to both to see if there is a difference...

Seee-ya,

Jim.

I've searched the forums high and low and I've learned everything about the Unichip except where to buy one and how much they cost.

Help me out here.

I run B map most of the time. For me, there's definately a difference between the two maps. Is your Power switch set correctly?(| vs. O). Are you making the switch between the maps with the engine off and key removed? Just a couple of thoughts.

I just installed a Unichip in my 04 DC 4.7. It is cramped to get the PnP module into, but it is done and I am excited to see any changes. Have driven around 6 times with MAP A and 3/4 throttle here and there, just mixed it up. The power seems to be better each day. After things have settled in to a routine, then I will switch to MAP B and see how it compares to A. So B is for BOMB huh? and A must be for just Allright. Well, my experaince is a flawless install, engine started and idled whisper quiet, snappy take off from the garage, shifts just before redline, consistantly (well sometimes after). Curious to see what B does. Seems like most posts indicate B has no problems or CEL. Jack seems like a commited man, and he spent 2 hours talking me through a Tundra engine control process. My head was spinning tables, inputs, outputs, closed/open loop etc. I cracked and bought one.

Map B requires high octane fuel -- map A but is for lower octane fuel.

To get the full effects of map B - I suggest adding Klotz octane booster as directed -- you can get it by the gallon here -- I run Klotz all the time and it is noticeable when I run it.

My map B (custom tuned unichip) is programmed for 95 octane and Klotz will boost it that high or higher.

KLOTZ OCTANE BOOSTER
Klotz is the leader and innovator in producing Octane Boosters and still the front runner in actual numbers of octane increased per ounce and cost effectiveness. Klotz Octane Booster provides extra strength in building octane and upper cylinder lubrication. One ounce per gallon of gasoline will raise the octane 2-1/2 numbers. Proper octane level helps eliminate pre-ignition and detonation, allowing engine to run cooler and to its fullest potential.

Klotz Octane Booster is environmentally safe and provides lubrication benefits equal to tetraethyl lead. Formulated to increase octane ratings of leaded or unleaded gasoline by 10 numbers or more if desired. Klotz Octane Booster is designed as a legal additive in all types of stock class racing. Adding more Octane Booster to gasoline than needed is not necessarily harmful, but simply becomes non-effective past a certain point. No more than 120 total octane can be achieved with gasoline as a fuel by nature. Using a significantly higher octane content than required can actually reduce power, as the effect of the slow burning fuel produces less combustion pressure. Klotz Octane Booster is also an excellent gasoline stabilizer preserving gasoline up to 16 months during storage.

Tests indicate the yield these added benefits...

* 1 oz. per gallon raises octane 2-1/2 numbers - 2 to 3 oz. per gallon produces significantly racy exhaust odor.

* Helps stop pre-ignition & detonation -Absorbs water condensation
* Helps stop engine run on & Cleans Fuel injectors
* Allows higher compression ratios & increases throttle response
* Provides upper cylinder lubrication equal to lead
* Preserves gasoline in fuel tank up to 16 months

PERFORMANCE APPLICATION DIRECTIONS: One ounce per gallon will raise the octane 2.5numbers, for racing add 3oz. per gal. of fuel. (Octane can be raised 10 numbers or more if desired). Experiment by trial and error to find the most suitable combination. To help eliminate varnish build-up in carburetor and fuel systems on a regular day to day basis, add one ounce to two gallons of gas periodically. Klotz Octane Booster has extra strength which makes it very effective & because of this it must be packaged in metal containers to maintain its strength. WARNING:DO NOT mix with Nitromethane, a violent reaction or explosion will occur. However, this product CAN be used with the Klotz NITRO Propanol additive as shown above.

STORAGE APPLICATION DIRECTIONS:Add one ounce per gallon to preserve gasoline from 6-8 months. Or two ounces per gallon for 12-16 months storage.

TECH TIP: KLOTZ OCTANE BOOSTER FOR OXYGENATED GAS

Klotz KL-602 Octane Booster is the perfect fix for the new government mandated oxygenated fuels in some states. These new clean burning fuels use Ethanol or MTBE (a form of alcohol/ether) and are putting racers and serious recreational users in a panic. High performance engines do not react favorably to these fuels because they tend to run lean. The chemical engineers at Klotz have the answer! Just add 1-2 ounces of Kl -602 per gallon of gasoline to control the burn speed of the gas and absorb any moisture that the alcohol will draw. This simple solution will save you thousands in engine repairs and still allow you to run your machines on the edge!
