Idk if they're underestimating it, or it really doesn't exist.
There's only a handful of hybrid or BT 1.8t's... (you have to assume at least a large percentage of them are active on the forums). Shapland (boss600?), Hornung (dbv2 V1), candyblanco (boss500 in Colorado), crxgator (but his is gone), and my car. Even if there's twice as many ghosts, that's 15 cars total. Call that a grand total of 8 Cobb units (because some would decide to go with already established tuners like UM).
The number of is38 and is20 cars is FAR greater, but there's enough off the shelf tuning options out there where it's not like cobb could steal a huge share. They're not gunna get the vast majority of the APR sales because it's marketed to a different crowd. They'll basically get uni sales, since it's a similar solution (remote flash). They won't get any of the JB4 sales because you can't self tweak.
It takes a fair amount of development, especially to release a real commercial product like an accessport. I just can't see them dedicating development time, documentation time, marketing time, etc to a product that's only had a dozen actual requests (especially when only a percentage of those people will actually be buyers). How many units would they actual sell in a calendar year? Are there 50 1.8t cars out there that don't have their needs met right now?
I've asked them many many times over the last 3 years (I keep replying to the same sales support request) and it's always the same.
For what it's worth... It's the same situation with ecutek at this point. Their last reply to me was that they don't have support for my box code and they likely won't this year. 5150 said we could just flash something from another box code (but I feel like if that were the case, then ecutek would have said they could do it).
This is why we're stuck with small companies for any real support - it's the only way to get someone to spend the time on it since they have less overhead and don't need to adhere to the same development / commercial product guidelines.
/rant. I just want my MPI to work.
