Electronic boost controller and TPS I need to modify or clamp down boost on my Dodge when at part throttle ( 1/4 or less ). Stoopid PCM is shutting down the engine when the stock MAP and TPS do not agree.
I was looking at the A'PEXi controllers but their website discourages use on non-Japanese cars. There definitely is no application for the Dodge truck! That and no dealer local could spell big warranty issues. GReedy's website is down right now.
The A'PEXi has a TPS signal monitor ( ascending, 0-5V, like the Dodge ) which would solve my dilemma, in theory.
Any of you out there with electronic controllers got some suggestions? Thanks for any help!

No reason why the Apexi wouldnt work. I would say the reason they mainly say for Jap cars, is that they provide wiring diags for them.
You can use either 0-5v or 5v-0 on the Apexi for TPS input.
Ive used them in a couple of Jap cars. Not the easiest thing to setup, and the instructions are a big help either.
Wiring them up is straightforward enough though.

I would have to aree we installed one in a Neon SRT4 recently and it worked good, the only thing else we needed was a tach adapter from MSD. We used the SAFCII controller that allowed moderate tuning for AFR as well!

Thx for the input everyone. I will try out the Turbosmart folks next. A'PEXi discouraged me from trying their product, mainly due to the warranty void if anything were to happen to the unit.
Stevieturbo, I am heading near Dublin in June, anything happening in the area? Got 4 weekends to kill.

Im about 100 miles away from Dublin myself, so couldnt say for sure.
All we do get here are poxy car shows with very little actually happening at them, and full of cars with cheesy bodykits, with engines from a hairdryer.

Unfortunately fuel prices, insurance, costs in general and lack of tracks all go against drag racing, and engine mods.
Here in Ireland/Northern Ireland we dont have any drag strips at all. They have attempted to run a couple of events on old airfields, but with limited success.
First was a total disaster, ruined by the organisers stupidity and complete lack of fore-sight as to what would happen. ( about 25k spectators turned up, yet there was about 200 pre-booked/pre-paid race entries ) They expected about 3-4k spectators. I emailed them before the event telling them what would happen, but they didnt listen, and ended up doing a runner, as the Police closed the event before it even got started, as the roads for miles around where in chaos, and the airfield was already full.
2nd wasnt too bad, but it rained all day, just after Xmas. ( different organisers )
Then just last week, they tried again, the weather was even worse....Pity, as weather before and after hasnt been bad.
They felt the need to bring Firestorm over ( Jet car ) and let it run in the rain, with is subsequently crashing and rolling, luckily nobody was injured.
If they had brains they would be dangerous.
