I understand that you are saying for the typical home wrencher its pretty simple, but for those who aren't (the vast majority that would be looking at your kit) it will be this much extra to install properly.Esmeril Racing wrote: 1) You guys will know installer rates far better than I so a $2000aus is probably accurate. We still recommend people install it on our own because we've found the following happen: a) many non-rotary shops do not read the install guide and cut corners since they think they know what they are doing b) the install is very easy and those who install it on their own follow the guide very carefully...problem free
2) Not that you are stating otherwise but we are very clear that the Microtech base map provided gets the car started and lets you run it very rich out of boost.
3) No Water/Meth is required we just recommend it over 7psi. Many customers are running at 12psi plus without it but they are tuned well. Water/meth is more of a safety net at lower psi levels...it can't hurt and if you make a mistake in tuning your engine is more likely to survive it.
4) We are first working on a Microtech solution for the SII...the MAF based tuning will follow on the SII but we know there are more challenges for the SII and the Microtech is a proven, reliable tuning solution where the stock ECU can't fiddle with injection/ignition (besides shutting it down if you trip an error such as different wheel speeds for front/back).
2) You make my point very very nicely. Who the heck wants to be driving around on a pig rich tune? with fuel cost at $1.50/litre (nearly $7 a gallon) it needs to be tuned to run appropriately as a daily driver.
3) Im confused here. This is pretty much standard on any FI engine.
4) Once again avoiding the specific question being asked. The SII cars (at least the AUDM ones do) have a safety mechanism built in which triggers a CEL if more than (I believe) 250g/sec of air is seen over the MAF. Unless you are unplugging the MAF (in which case you will get a CEL) you are going to get this "To much air" CEL regardless of MAF or MAP based tuning. Have you found a way to over come this issue.
We are not trying to contradict you or dismiss what you have to say, we are honestly just trying to answer any questions people have and give insight into experiences we've had with the RX-8 with or without a turbo kit. Your experiences may be different and some of what we are stating may not apply to aussie RX-8s, that is why we appreciate your feedback on our posts.
We'll clarify so what we posted makes more sense:
1) Most turbo kits are difficult to install and require various modifications to the car to make it work. The reason ours is so easy to install is due to: a) a very open engine bay and easily uninstalled stock components thanks to Mazda's engineers b) this let us engineer not just a turbo kit but a system of installation that is very easy...I'd be happy to send you the full color install guide pdf for you to review. It isn't magic, it takes a lot of time...a full weekend of working all day long...but it is easy to follow along and not make mistakes.
-Another note...in the US the RX-8 is very inexpensive so many customers are buying the car used for $10,000usd (that includes taxes)...so they want to save money and install it on their own. Installing it is actually fun to do and you get to know the car so we'd still recommend installing it on your own even if you had the money to ship it to the US and have Esmeril Racing install it then ship it back .
2) As you are suggesting Ideally you'd have a tuner tune your car after the kit is installed, let it break in, then do a final tune. If a tuner costs $250 for each visit, fuel costs around an additional $80 for the break in period, potentially you are saving $170. That isn't perfect science but it is close.
3) Just wanted clarify so that no one thinks they have to run it with a meth/water injection...some tuners think the RX-8 tunes like an RX-7 so meth is not needed in the 15psi range, with the higher compression of the RX-8 we highly recommend it.
4) We have never suggested that you wouldn't throw a CEL. In US cars this causes no changes operation and is something to expect with a turbo kit that produces over 300whp in an RX-8. You can modify the intercooler piping to eliminate the cel but since a cel will not adversely impact the operation of the Microtech it is not needed. With a MAF based tuning solution we will have a specialized intake pipe to provide a proper reading for the MAF. There are Microtech tuners all over Australia so we'd probably still recommend a Microtech for you guys.
