Ground floor, this should be excellent. At one point AI was pushing me to do this swap on my MSP, I shall live vicariously through you.

ionn posted:Won't that mess with the fuelling though? I mean, when there is exhaust gas passed to the intake, there's less air/oxygen and the ECU would believe it's supposed to have less fuel. Or will it just work anyway since there actually won't be less air going through the MAF? Pretty sure such an old computer isn't doing any kind of work to factor in specific EGR flow, it's just going off a map of IF (condition == x) {egr = Y} and dutifully fuelling off the MAF signal like always. It depends on the manufacturer, but that ECU might not even be OBD2 compliant yet; older stuff, the error checking basically consisted of a continuity test through the appropriate device, maybe some rudimentary current monitoring if you're feeling fancy. Complicated feedback sensor loops ensuring various emissions controls were actually achieving their desired effect weren't around for at least a few more years.

Yup, the surface area of the tubes + radiator fan airflow does more than you'd think.
