Dyno

Hondata is the world leader‚ in tuning Honda engines and have many‚ world records‚ to prove this. Every map listed here has been comprehensively tuned for fuel, ignition and boost.

Listed here are dyno plots of several of the many base maps provided with the FlashPro.‚

How the FlashPro will perform on a stock Civic Si ?‚ The answer is superbly!

With a 100% stock ‚ Civic Si Turbo you will benefit from:

  • ‚ 27 HP and 40 lb-ft torque
  • Improved turbo spool
  • Raised boost limits
  • Better throttle response
  • Better mid range power and torque
  • Removed speed limit
  • No change in part throttle fuel economy
  • World class datalogging - which will teach you a lot about your engine.

Base map:

  • Dotted green line stock Si. 205 hp 235 lb-ft torque.
  • Solid green line Hondata +6 psi reflash. 233 hp 258 lb-ft torque


+ 9 PSI calibration

The supplied ‚ +9 psi calibration (light blue line) is capable of generating 272 lb-ft torque.‚ In our dyno testing we found the stock clutch beginning to slip. The Dynapack dyno is very hard on the drivetrain and is more likely ‚ to cause slip than street driving with stock tires. Our road testing to date has shown no clutch slip with the + 9 psi calibration. We recommend using the +6 psi calibration and an upgraded clutch.

Mitsubishi Turbo Si calibration

Stock cat, intake and exhaust. 93 octane.

Clutch recommended

  • Dashed green line stock Si. 205 hp 235 lb-ft torque.
  • Dotted red line Mitsubishi turbo. 250 hp 275 lb-ft torque

PASSED MY INSPECTION! THIS PRODUCT WORKS LIKE A MIRACLE DONT HESITATE TO BUY IT!
Inspection on my car due the end of January! My check engine light was coming on so I checked with a code reader & found it was a P0420. Read about the Catalytic Converter System possibly being in need of replacement or perhaps clogged. I am a woman, and know next to ZERO about cars, but I can read. Did investigate and found that the replacement of a Catalytic Converter system is mad expensive- also found this Moly Cleaner to add to gas tank. I'm not going to lie; I was nervous as I have a Kia Rio 2014 that has a very small gas tank and gets great gas mileage. In reading the consensus seemed to be to add to 1/4 tank of gas and drive fast for good periods of time to blow out the clog (if it was a clog). Did I mention I live in NYC and driving for long periods of time at high speeds can be a problem because of terrible traffic. Anyhow, this Saturday I poured the can into my 1/2 filled tank and hit a parkway near my home early morning. I did drive for 45 miles sometimes at 80mph then 60mph but tried to do it for a good few minutes at a time without getting pulled over. Checked my reader again, and it was not quite ready but the engine light did stay off. Next day, drove to work, stuck in traffic somewhat & never made it over 20mph & checked my reader again- all good to go for inspection. Went last night- my car PASSED and got that sticker in my window- so I am good for another year. The BEST money I have spent all year. Thank you for carrying this product! Saved me thousands! DONT HESITATE TO USE THIS. The hardest part for me was removing the cap on the can!

Great stuff
Seemed to work as well as or better than some more expensive catalytic converter cleaners. I put it in while at 1/3 tank and my Check Engine light went out almost immediately once I started driving. My Tundra has almost 230,000 miles and still runs great but was getting a little harder to start after I switched from full synthetic oil to conventional. I’ll never do that again and immediately switched back but the damage was done. Check engine light came on and I had to crank longer to get it started. Adding this Liquid Moly fixed both issues temporarily. I have to wonder if this was used regularly, say every 3 months, if it would clean the catalytic converter more permanently?

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional. When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use. The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings. The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use. Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
