Hey guys if anyone can help with suggestions. I have both Hondata V1 ecu and a Neptune demon P28 ecu new from HR tuning. Im ready to get my car tuned and ive only found 1 tuner in the area (Nj-Philadelphia) who tunes with neptune. Others tell me to stick with hondata. Im only asking because ive had Neptune in the past no issues and i loved it specially the adjustable launch control. My car is a Gsr Css block w/6262 turbo with a goal 450-500whp. Would i be fine with either? or any reason why i should stay with hondata?
Thank you.

 

The Hondata V1 needs to be upgraded before the internal battery fails and you start having tune-retention issues. Both systems have more than enough features to effectively tune your combination... the best choice is the one that your tuner is most comfortable tuning. Hondata has "the adjustable launch control" too... so don't let that influence your decision.

 

You can buy the v1 s300 batteries and solder them in no problem. I prefer Hondata, that seems to be what most tuners local to me use

 

I've had both, on 2 different engine setups and cars. Either one will work fine but I like the Neptune better due to newer technology and a bit more options.

 

Thanks everyone. I didnt kno the s300 has batteries. Im still stuck on which direction to go.. maybe get a. Newer v3 or stay with my neptune.

 

Just curious... What is "newer" about the Demon board and exactly what options does the Neptune software have that Hondata doesn't ???

 

Only the s300 v1 had an internal memory battery. This system was converted to a more modern system in the v2+ versions. Hondata offers an upgrade option for v1 owners if you choose to use that system. From the "HOME" page, click on "Support", "Manuals and Forms", and then the "s300 v3 Upgrade Form". Print that form off, fill it out and send it directly to Hondata. The cost is between $290 and $305 depending on where you live in the Continental 48 States... assuming your current v1 still works. Otherwise, it adds $100 to the cost to upgrade.

 

datalogging options. From what I recall the V1 version of Hondata didn't have it. Plus, the price on Hondata is basically the same across the board. You can find Neptune from various sellers at better pricing.

 

It does?

 

Unless your definition of adjustable and mine differ... I would say yes absolutely.

 

Neptune can have a variable launch control. You set minimum rpm it will engage and then any rpm with x amount of tps input it will hold that rpm to launch at.

 

Personally I like Neptune. I use it on my personal car and recommend it to all my customers.
